+Change Log
+==========
+
+All relevant changes are documented in this file.
+
+
+[2.2][] - 2015-11-23
+--------------------
+
+Lots of fixes to handle static builds, but also fixes for dynamic event
+handling and reconfiguration at runtime.
+
+### Changes
+
+* Upgrade to libuEv v1.2.4, to handle static builds
+* Upgrade to libite (LITE) v1.2.0, to handle static builds
+* Clarify how to select different plugins with the configure script
+* Improve urandom plugin for embedded systems w/o random seed
+* Add `--debug` flag to `initctl`
+* The runlevels listed for services in `initctl show` now hightlight the
+  active runlevel.
+* Clarify in the README and in `initctl help` that the GW event to
+  listen for in service declarations is `GW:UP`
+
+### Fixes
+
+* Build fixes for `configure --disable-inetd`
+* Fixed issue #14: Improved support for static Finit builds
+* Misc. fixes to silence warnings when building a static Finit
+* Default to register services as `SIGHUP`'able, regression in v2.0
+* Call `HOOK_SVC_RECONF` only when all processes have been stopped
+* On reload/reconf we must wait for all services to stop first
+* Only trigger on events that matches the service's specification,
+  fix by Tobias Waldekranz
+
+
+[2.1][] - 2015-10-16
+--------------------
+
+### Changes
+
+* Add hook point for fstab mount failure
+* Set hostname on dynamic reload
+* Upgrade to libite v1.1.1
+
+### Fixes
+
+* Fix service callback coredump checks and simplify callback exit
+* Do not use `-Os` use `-O2` as default optimization level.  Many cross
+  compiler toolchains are known to have problems with `-Os`
+* Do not allow build VERSION to be overloaded by an environment variable
+* Fix too small MAX arguments and too few argments in `svc_t` for
+  reading currently running services with `initctl show`
+* Unblock blocked signals after forking off a child
+
+
+[2.0][] - 2015-09-20
+--------------------
+
+Support for multiple instances and event based services, as well as the
+introduction of an `initctl` tool.
+
+**Note:** Incompatible change to syntax for custom `inetd` services,
+  c.f. Finit v[1.12][].
+
+### Changes
+* The most notable change is the support for multiple instances.  A must
+  have when running multiple DHCP clients, OpenVPN tunnels, or anything
+  that means using the same command only with different arguments.  Now
+  simply add a `:ID` after the `service` keyword, where `ID` is a unique
+  instance number for that service.
+
+        service :1 [2345] /sbin/httpd -f -h /http -p 80   -- Web server
+        service :2 [2345] /sbin/httpd -f -h /http -p 8080 -- Old web server
+
+* Another noteworthy new feature is support for starting/stopping
+  services on Netlink events:
+
+        service :1 [2345] <!IFUP:eth0,GW> /sbin/dropbear -R -F -p 22 -- SSH daemon
+
+  Here the first instance `:1` of the SSH daemon is declared to run in
+  runlevels 2-5, but only if eth0 `IFUP:eth0` is up and a gateway `GW`
+  is set.  When the configuration changes, a new gateway is set, or if
+  somehow a new `IFUP` event for eth0 is received, then dropbear is not
+  SIGHUP'ed, but instead stop-started `<!>`.  The latter trick applies
+  to all services, even those that do not define any events.
+* Support for reloading `*.conf` files in `/etc/finit.d/` on SIGHUP.
+  All `task`, `service` and `run` statements can be used in these .conf
+  files.  Use the `telinit q` command, `initctl reload` or simply send
+  `SIGHUP` to PID 1 to reload them.  Finit automatically does reload of
+  these `*.conf` files when changing runlevel.
+* Support for a modern `initctl` tool which can stop/start/reload and
+  list status of all system services.  Also, the old client tool used
+  to change runlevel is now also available as a symlink: `telinit`.
+
+        initctl [-v] <status|stop|start|reload|restart> [JOB]
+
+* Add concept of "jobs".  This is a unique identifier, composed of a
+  service and instance number, `SVC:ID`
+
+        initctl <stop|start|reload|restart> JOB
+
+* Support for *deny filters* in `inetd` services.
+
+        inetd service/proto[@iface,!iface,...] </path/to/cmd | internal[.service]>
+
+  Internal services on a custom port must use the `internal.service`
+  syntax so Finit can properly bind the inetd service to the correct
+  plugin.  Here follows a few examples:
+
+        inetd time/udp                    wait [2345] internal                -- UNIX rdate service
+        inetd time/tcp                  nowait [2345] internal                -- UNIX rdate service
+        inetd 3737/tcp                  nowait [2345] internal.time           -- UNIX rdate service
+        inetd telnet/tcp@*,!eth1,!eth0, nowait [2345] /sbin/telnetd -i -F     -- Telnet service
+        inetd 2323/tcp@eth1,eth2,eth0   nowait [2345] /sbin/telnetd -i -F     -- Telnet service
+        inetd 222/tcp@eth0              nowait [2345] /sbin/dropbear -i -R -F -- SSH service
+        inetd ssh/tcp@*,!eth0           nowait [2345] /sbin/dropbear -i -R -F -- SSH service
+
+  Access to telnet on port `2323` is only possible from interfaces
+  `eth0`, `eth1` and `eth2`.  The standard telnet port (`23`) is
+  available from all other interfaces, but also `eth2`.  The `*`
+  notation used in the ssh stanza means *any* interface, however, here
+  `eth0` is not allowed.
+
+  **NOTE:** This change breaks syntax compatibility with Finit v[1.12].
+* Support for a more user-friendly configure script rather than editing
+  the top Makefile, or setting environment variables at build time.
+* Support for building Finit statically, no external libraries.  This
+  unfortunately means that some plugins cannot be built, at all.
+  Big thanks goes to James Mills for all help testing this out!
+* Support for disabling the built-in inetd server with `configure`.
+* Support for two new hook points: `HOOK_SVC_RECONF` and
+  `HOOK_RUNLEVEL_CHANGE`.  See the source for the exact location.
+* The `include <FILE>` option now needs an absolute path to `FILE`.
+
+### Fixes
+* Rename `patches/` to `contrib/` to simplify integration in 3rd party
+  build systems.
+* Fix for unwanted zombies ... when receiving SIGCHLD we must reap *all*
+  children.  We only receive one signal, but multiple processes may have
+  exited and need to be collected.
+
+
+[1.12][] - 2015-03-04
+---------------------
+
+The inetd release.
+
+### Changes
+* Add support for built-in inetd super server -- launch services on
+  demand.  Supports filtering per interface and custom Inet ports.
+* Upgrade to [libuEv] v1.1.0 to better handle error conditions.
+* Allow mixed case config directives in `finit.conf`
+* Add support for RFC 868 (rdate) time plugin, start as inetd service.
+* Load plugins before parsing `finit.conf`, this makes it possible to
+  extend finit even with configuration commands.  E.g., the `time.so`
+  plugin must be loaded for the `inetd time/tcp internal` service to be
+  accepted when parsing `finit.conf`.
+* Slight change in TTY fallback behavior, if no TTY is listed in the
+  system `finit.conf` first inspect the `console` setting and only if
+  that too is unset fall back to `/bin/sh`
+* When falling back to the `console` TTY or `/bin/sh`, finit now marks
+  this fallback as console.  Should improve usability in some use cases.
+
+### Fixes
+* Revert "Use vfork() instead of fork() before exec()" from v1.11.  It
+  turned out to not work so well after all.  For instance, launching
+  TTYs in a background process completely blocked inetd services from
+  even starting up listening sockets ... proper fork seems to work fine
+  though.  This is the casue for *yanking* the [1.11] release, below.
+* Trap segfaults caused by external plugins/callbacks in a sub-process.
+  This prevents a single programming mistake in by a 3rd party developer
+  from taking down the entire system.
+* Fix Coverity CID 56281: dlopen() resource leak by storing the pointer.
+  For the time being we do not support unloading plugins.
+* Set hostname early, so bootstrap processes like syslog can use it.
+* Only restart *lost daemons* when recovering from a SIGSTOP/norespawn.
+
+
+[1.11][] - 2015-01-24 [YANKED]
+------------------------------
+
+The [libuEv] release.
+
+**Note:** This release has been *yanked* from distribution due to a
+  regression in launching background processes and TTY's.  Fixed in
+  Finit v[1.12].
+
+### Changes
+* Now using the asynchronous libuEv library for handling all events:
+  signals, timers and listening to sockets or file descriptors.
+* Rename NEWS.md --> CHANGELOG.md, with symlinks for `make install`
+* Attempt to align with http://keepachangelog.com/ for this file.
+* Travis CI now only invokes Coverity Scan from the 'dev' branch.  This
+  means that all development, except documentation updates, must go into
+  that branch.
+
+### Fixes
+* Fix bug with finit dying when no `tty` is defined in `finit.conf`, now
+  even the fallback shell has control over its TTY, see fix in GIT
+  commit [dea3ae8] for this.
+
+
+[1.10][] - 2014-11-27
+---------------------
+
+Major bug fix release.
+
+### Changes
+* Project now relies on static code analysis from Coverity, so this
+  release contains many serious bug fixes.
+* Convert to use Markdown for README, NEWS and TODO.
+* Serious update to README and slight pruning of finished TODO items.
+
+### Fixes
+* Fix serious file descriptor and memory leaks in the following
+  functions.  In particular the leaks in `run_interactive()` are very
+  serious since that function is called every time a service is started
+  and/or restarted!  For details, see the GIT log:
+  * `helpers.c:run()`
+  * `helpers.c:run_interactive()`
+  * `helpers.c:set_hostname()`
+  * `helpers.c:procname_kill()`
+* `svc.c:svc_start()`: Fix swapped arguments to dup2() and add close(fd)
+  to prevent descriptor leak.
+* `svc.c:svc_start()`: Fix out of bounds write to local stack variable,
+  wrote off-by-one outside array.
+* Several added checks for return values to `mknod()`, `mkdir()`,
+  `remove()`, etc.
+
+
+[1.9][] - 2014-04-21
+--------------------
+
+### Changes
+* Add support for an include directive to `.conf` files
+* Fallback to `/bin/sh` if user forgets tty setting
+* Initial support for restarting lost services during `norespwan`
+
+### Fixes
+* Bug fixes, code cleanup
+* Handle `SIGHUP` from service callback properly when switching runlevel
+* Misc. major (memleak) and minor fixes and additions to `libite/lite.h`
+
+
+[1.8][] - 2013-06-07
+--------------------
+
+### Changes
+* Support for runlevels, with a bootstrap runlevel 'S'
+* Support for saving previous and current runlevel to UTMP
+* Support for new `finit.conf` commands: run, task, and runlevel
+* Support for tty and console commands in `finit.conf`, like services
+  but for launching multiple getty logins
+* New tty plugin to monitor TTYs coming and going, like USB TTYs
+
+### Fixes
+* Bugfixes to libite
+
+
+[1.7][] - 2012-10-08
+--------------------
+
+### Changes
+* Show `__FILE__` in `_d()` debug messages, useful for plugins with
+  similarily named callbacks. Also, only in debug mode anyway
+* Make sure to cleanup recorded PID when a service is lost.  Required by
+  service plugins for their callbacks to work.
+* Only clear screen when in verbose mode. Maybe this should be removed
+  altogether?
+
+### Fixes
+* Bugfix: Do not `free()` static string in `finit.conf` parser
+
+
+[1.6][] - 2012-10-06
+--------------------
+
+### Changes
+* Skip `.` and `..` in plugin loader and display error when failing to
+  load plugins
+* Support for overriding `/etc/finit.d` with `runparts DIR` in
+  `finit.conf`
+* Revoke support for starting services not starting with a slash.
+* Prevent endless restart of non-existing services in `finit.conf`
+* Support for sysvinit style startstop scripts in `/etc/finit.d`
+
+### Fixes
+* Minor fix to alsa-utils plugin to silence on non-existing cards
+
+
+[1.5][] - 2012-10-03
+--------------------
+
+### Changes
+* Use bootmisc plugin to setup standard FHS 2.3 structure in `/var`
+* Added `FLOG_WARN()` syslog macro, for plugins
+* Add plugin dependency resolver. Checks `plugin_t` for `.depends`
+
+
+[1.4][] - 2012-10-02
+--------------------
+
+### Changes
+* Start refactoring helpers.c into a libite.so (-lite).  This means
+  other user space applications/daemons can make use of the neat toolbox
+  available in finit
+* Use short-form -s/-w -u to work with BusyBox hwclock as well
+* Use RTLD_GLOBAL flag to tell dynamic loader to load dependent .so
+  files as well.  Lets other plugins use global symbols.
+* Greatly simplify svc hook for external plugins and cleanup plugin API.
+* And more ... see the GIT log for more details.
+
+### Fixes
+* Fix I/O plugin watcher and load plugins earlier for a new hook
+
+
+[1.3][] - 2012-09-28
+--------------------
+
+### Changes
+* Cleanup public plugin API a bit and add new pid/pidfile funcs
+* Add plugin hook to end of service startup

+  install-data, and install-dev targets in Makefile.  Useful if you want
+  to call targets with different `$DESTDIR`!
+* Makefile fixes for installation, paths encoded wrong
+* Strip binaries + .so files, support for `$(CROSS)` toolchain strip
+* Default install is now to `/sbin/finit` and `/usr/`
+* Note change in `$PLUGIN_DIR` environemnt variable to `$plugindir`

-Finit is a reimplementation of the Eeepc "fastinit" program based on its
-system calls with gaps filled with frog DNA.
-
-Finit's purpose is to build upon the general workings of fastinit and
-improve/optimize it for Xandros or alternative distributions running on
-the Eeepc. Finit comes in three flavors: finit is a replica of the Asus
-fastinit, finit-mod is an improved drop-in replacement for fastinit,
-and finit-alt is a generic replacement for other systems. Finit-mod
-and finit-alt were much improved with patches from Metalshark. 
-
-See more information at http://helllabs.org/finit/
-
-
-Usage scenarios
----------------
-
-1. Replace the original Eeepc 702 fastinit (finit-mod)
-
-2. Allow fast booting in alternative Linux distributions running on the
-   Eeepc and other netbooks (finit-alt)
-
-
-Finit-alt is distribution-specific. Currently it generates a finit-mdv
-executable for Mandriva 2008/2008.1 systems. Smurfy ported it to
-eeeXubuntu, and parts of his port have been merged to finit-alt.
-
-
-Finit-alt features
-------------------
-
-Finit-alt reads configuration information from /etc/finit.conf. See
-the source code for available options.
-
-
-Rebooting and halting
----------------------
-
-Finit handles SIGUSR1 and SIGUSR2 for reboot and halt, and listens to
-/dev/initctl so standard Linux reboot and halt commands should also
-work.
-
-
-Debugging
----------
-
-Add finit_debug to the kernel parameter line to enable trace messages
-and to run a shell after the X server.

+Introduction
+------------
+
+Init is the first userland process started by the UNIX kernel, therefore
+it always has PID 1 and is responsible for starting up the rest of the
+system.
+
+Finit is a plugin-based init with [process supervision][1] similar to
+that of D.J. Bernstein's [daemontools][2] and Gerrit Pape's [runit][3].
+The main focus of Finit is on small and embedded GNU/Linux systems, yet
+fully functional on standard server and desktop installations as well.
+
+Traditional [SysV init][4] style systems are scripted.  For low-resource
+embedded systems this can be quite resource intensive and cause longer
+boot times.  Finit is optimized to reduce context switches and forking
+of processes to provide a very basic bootstrap written entirely in C.
+
+> Finit basically does everything you need from its `main()` function!
+
+Hence, there is no `/etc/init.d/rcS` script, or similar, instead Finit
+reads its configuration from [/etc/finit.conf](#etcfinitconf).  This
+file details what kernel modules to load, programs to run, daemons to
+supervise, and inetd services to launch on demand.
+
+See [TroglOS][9] for an example of how to boot a small embedded system
+with Finit.
+
+
+Features
+--------
+
+**Process Supervision**
+
+Start, monitor and restart processes (daemons) if they fail.
+
+
+**Inetd**
+
+Finit comes with a built-in `inetd` server.  No need to maintain a
+separate config file for services that you want to start on demand.
+
+All inetd services started can be filtered per port and inbound
+interface, reducing the need for a full blown firewall.
+
+
+**Runlevels**
+
+Runlevels are optional in Finit, but support for [SysV runlevels][5] is
+available if needed.  All services in runlevel S(1) are started first,
+followed by the desired run-time runlevel.  Runlevel S can be started in
+sequence by using `run [S] cmd`.  Changing runlevels at runtime is done
+like any other init, e.g. <kbd>init 4</kbd>
+
+
+**Plugins**
+
+Finit plugins can be *callbacks*, *boot hooks* into different stages of
+the boot process, or *pure extensions*.  Plugins are written in C and
+compiled into a dynamic library that is loaded automatically by finit at
+boot.  A basic set of plugins that extend and modify the basic behavior
+are bundled in the `plugins/` directory.
+
+Capabilities:
+
+- **Task/Run/Service callbacks**  
+  Modify service arguments, override service monitor's decisions to
+  start/stop/reload a service.
+- **Hooks**  
+  Hook into the boot at predefined points to extend Finit
+- **I/O**  
+  Listen to external events and control Finit behavior/services
+- **Inetd**  
+  Extend Finit with internal inetd services, for an example, see
+  `plugins/time.c`
+
+Extensions and functionality not purely related to what an `/sbin/init`
+needs to start a system are available as a set of plugins that either
+hook into the boot process or respond to various I/O.
+
+
+/etc/finit.conf
+---------------
+
+Contrary to most other script based init alternatives ([SysV init][4],
+[upstart][6], [systemd][7], [OpenRC][8], etc.)  Finit reads its entire
+configuration from `/etc/finit.conf`.
+
+The command line arguments given in `/etc/finit.conf` to each service
+provide a default.  A plugin can be used to register a callback to a
+service and then modify the behavior to suit the current runlevel and
+system configuration.
+
+For instance, before starting a heavily resource intensive service like
+IPsec or OpenVPN, a callback can check if the outbound interface is up
+and has an IP address, or just check if the service is disabled — much
+like what a SysV init start script usually does.
+
+Syntax:
+
+* `check <DEV>`  
+  Run fsck on a file system before mounting it
+
+* `module <MODULE>`  
+  Load a kernel module, with optional arguments
+
+* `network <PATH>`  
+  Script or program to bring up networking, with optional arguments
+
+* `runlevel <N>`  
+  N is the runlevel number 1-9, where 6 is reserved for reboot.  
+  Default is 2.
+
+* `run [LVLS] /path/to/cmd ARGS -- Optional description`  
+  One-shot command to run in sequence when entering a runlevel, with
+  optional arguments and description.  This command is guaranteed to be
+  completed before running the next command.
+
+* `task [LVLS] /path/to/cmd ARGS -- Optional description`  
+  One-shot like 'run', but starts in parallel with the next command
+
+* `service [LVLS] /path/to/daemon ARGS -- Optional description`  
+  Service, or daemon, to be monitored and automatically restarted if it
+  exits prematurely.  Please note that you often need to provide a
+  `--foreground` or `--no-background` argument to most daemons to
+  prevent them from forking off a sub-process in the background.
+
+* `inetd service/proto[@iflist] <wait|nowait> [LVLS] /path/to/daemon args`  
+  Launch a daemon when a client initiates a connection on an Internet
+  port.  Available services are listed in the UNIX `/etc/services` file.
+  Finit can filter access to from a list of interfaces, `@iflist`, per
+  inetd service as well as listen to custom ports.
+
+```shell
+        inetd ftp/tcp	nowait	@root	/usr/sbin/uftpd -i -f
+        inetd tftp/udp	wait	@root	/usr/sbin/uftpd -i -t
+```
+
+  The following example listens to port 2323 for telnet connections and
+  only allows clients connecting from `eth0`:
+
+```shell
+        inetd 2323/tcp@eth0 nowait [2345] /sbin/telnetd -i -F
+```
+
+  The interface list, `@iflist`, is of the format `@iface,!iface,iface`,
+  where a single `!` means to deny access.  Notice how interfaces are
+  comma separated with no spaces.
+
+  The `inetd` directive can also have ` -- Optional Description`, only
+  Finit does not output this text on the console when launching inetd
+  services.  Instead this text is sent to syslog and also shown by the
+  `initctl` tool.  More on inetd below.
+
+* `runparts <DIR>`  
+  Call run-parts(8) on a directory to run start scripts.  All executable
+  files, or scripts, in the directory are called, in alphabetic order.
+
+* `include <CONF>`  
+  Include another configuration file.  Absolute path required.
+
+* `tty [LVLS] <DEV | /path/to/cmd [args]>`  
+  Start a getty on the given TTY device DEV, in the given runlevels.  If
+  no tty setting is given in `finit.conf`, or if `/bin/sh` is given as
+  argument instead of a device path, a single shell is started on the
+  default console.  Useful for really bare-bones systems.
+  
+  It is also possible to supply the full command line, with arguments,
+  to your getty.  In this case finit will simply use that command.
+  
+  See `finit.h` for the `#define GETTY` that is called, along with the
+  default baud rate.
+
+* `console <DEV | /path/to/cmd [args]>`  
+  Some embedded systems have a dedicated serial console/service port.
+  This command tells finit to not start getty directly, since there may
+  not be anyone there.  To save RAM and CPU finit instead displays a
+  friendly message and waits for the user to activate the console with a
+  key press before starting getty.  Finit also does some other magic and
+  changes the process name to "console".
+  
+  Like the `tty` command, the `console` command can also be used to
+  simply start a UNIX shell, e.g. `/bin/sh`.
+
+When running <kbd>make install</kbd> no default `/etc/finit.conf` will
+be installed since system requirements differ too much.  Try out the
+Debian 6.0 example `/usr/share/doc/finit/finit.conf` configuration that
+is capable of service monitoring SSH, sysklogd, gdm and a console getty!
+
+Every `run`, `task`, `service`, or `inetd` can also list the privileges
+the `/path/to/cmd` should be executed with.  Simply prefix the path with
+`[@USR[:GRP]]` like this:
+
+```shell
+    run [2345] @joe:users /usr/bin/logger "Hello world"
+```
+
+For multiple instances of the same command, e.g. a DHCP client or
+multiple web servers, add `:ID` somewhere between the `run`, `task`,
+`service` keyword and the command, like this:
+
+```shell
+    service :1 [2345] /sbin/httpd -f -h /http -p 80   -- Web server
+    service :2 [2345] /sbin/httpd -f -h /http -p 8080 -- Old web server
+```
+
+Without the `:ID` to the service the latter will overwrite the former
+and only the old web server would be started and supervised.
+
+
+/etc/finit.d
+------------
+
+Finit supports changes to the overall system configuration at runtime.
+For this purpose the (configurable) directory `/etc/finit.d` is used.
+Here you can put configuration file snippets, one per service if you
+like, which are all sourced automatically by finit at boot when loading
+the static configuration from `/etc/finit.conf`.  This is the default
+behavior, so no include directives are necessary.
+
+To add a new service, simply drop a `.conf` file in `/etc/finit.d` and
+send `SIGHUP` to PID 1, or call `finit q`.  Any service read from this
+directory is flagged as a dynamic service, so changes to their `.conf`
+files, or even removal of the files, is detected at `SIGHUP`.
+
+- If a service's `.conf` file has been removed, the service is stopped.
+- If the file is modified, the service is reloaded, stopped and started.
+- If a new service is detected, it is started — respecting runlevels
+  and return values from any callbacks.
+
+The `/etc/finit.d` directory was previously the default Finit `runparts`
+directory.  Finit no longer has a default `runparts`, so make sure to
+update your setup, or the finit configuration, accordingly.
+
+**Note:** Configurations read from `/etc/finit.d` are read *after*
+  initial bootstrap, runlevel S(1).  Hence, bootstrap services *must* be
+  in `/etc/finit.conf`!
+
+
+Runparts
+--------
+
+At the end of the boot, when networking and all services are up, finit
+calls its built-in [run-parts(8)][] on the `runparts <DIR>` directory,
+if it exists.  Similar to how the `/ec/rc.local` file works in most
+other init daemons, only finit runs a directory of scripts.  This
+replaces the earlier support for a `/usr/sbin/services.sh` script in the
+original finit.
+
+
+Bootstrap
+---------
+
+1. Populate `/dev`
+2. Parse `/etc/finit.conf`
+3. Load all `.so` plugins
+4. Remount/Pivot `/` to get R+W
+5. Call 1st level hooks, `HOOK_ROOTFS_UP`
+6. Mount `/etc/fstab` and swap, if available
+7. Cleanup stale files from `/tmp/*` et al
+8. Enable SysV init signals
+9. Call 2nd level hooks, `HOOK_BASEFS_UP`
+10. Start all 'S' runlevel tasks and services
+11. Load kernel parameters from `/etc/sysctl.conf`
+12. Set hostname and bring up loopback interface
+13. Call `network` script, if set in `/etc/finit.conf`
+14. Call 3rd level hooks, `HOOK_NETWORK_UP`
+15. Load all `*.conf` files in `/etc/finit.d/` and switch to the active
+    active runlevel, as set in `/etc/finit.conf`, default is 2.  Here is
+    where the rest of all tasks and inetd services are started.
+16. Call 4th level hooks, `HOOK_SVC_UP`
+17. If `runparts <DIR>` is set, [run-parts(8)][] is called on `<DIR>`
+18. Call 5th level (last) hooks, `HOOK_SYSTEM_UP`
+19. Start TTYs defined in `/etc/finit.conf`, or rescue on `/dev/console`
+20. Enter main monitor loop
+
+In (10) and (15) tasks and services defined in `/etc/finit.conf` are
+started.  Remember, all `service` and `task` stanzas are started in
+parallel and `run` in sequence, and in the order listed.  Hence, to
+emulate a SysV `/etc/init.d/rcS` one could write a long file with only
+`run` statements.
+
+Notice the five hook points that are called at various point in the
+bootstrap process.  This is where plugins can extend the boot in any way
+they please.
+
+For instance, at `HOOK_BASEFS_UP` a plugin could read an XML file from a
+USB stick, convert/copy its contents to the system's `/etc/` directory,
+well before all 'S' runlevel tasks are started.  This could be used with
+system images that are created read-only and all configuration is stored
+on external media.
+
+
+Runlevels
+---------
+
+Basic support for [runlevels][5] is included in Finit from v1.8.  By
+default all services, tasks, run commands and TTYs listed without a set
+of runlevels get a default set `[234]` assigned.  The default runlevel
+after boot is 2.
+
+Finit supports runlevels 0-9, and S, with 0 reserved for halt, 6 reboot
+and S for services to only run at bootstrap.  Runlevel 1 is the single
+user level, where usually no networking is enabled.  In Finit this is
+more of a policy for the user to define.  Normally only runlevels 1-6
+are used, and even more commonly, only the default runlevel is used.
+
+To specify an allowed set of runlevels for a `service`, `run` command,
+`task`, or `tty`, add `[NNN]` to your `/etc/finit.conf`, like this:
+
+```shell
+    service [S12345] /sbin/syslogd -n -x     -- System log daemon
+    run     [S]      /etc/init.d/acpid start -- Starting ACPI Daemon
+    task    [S]      /etc/init.d/kbd start   -- Preparing console
+    service [S12345] /sbin/klogd -n -x       -- Kernel log daemon
+    tty     [12345]  /dev/tty1
+    tty     [2]      /dev/tty2
+    tty     [2]      /dev/tty3
+    tty     [2]      /dev/tty4
+    tty     [2]      /dev/tty5
+    tty     [2]      /dev/tty6
+```
+
+In this example syslogd is first started, in parallel, and then acpid is
+called using a conventional SysV init script.  It is called with the run
+command, meaning the following task command to start the kbd script is
+not called until the acpid init script has fully completed.  Then the
+keyboard setup script is called in parallel with klogd as a monitored
+service.
+
+Again, tasks and services are started in parallel, while run commands
+are called in the order listed and subsequent commands are not started
+until a run command has completed.
+
+Switching between runlevels can be done by calling init with a single
+argument, e.g. <kbd>init 5</kbd> switches to runlevel 5.  When changing
+runlevels Finit also automatically reloads all `.conf` files in the
+`/etc/finit.d/` directory.  So if you want to set a new system config,
+switch to runlevel 1, change all config files in the system, and touch
+all `.conf` files in `/etc/finit.d` before switching back to the
+previous runlevel again — that way Finit can both stop old services and
+start any new ones for you, without rebooting the system.
+
+
+Inetd
+-----
+
+A built-in *Internet Super Server* support was added in Finit v1.12 and
+v1.13, along with an internal `time` inetd service, RFC 868 (rdate).
+The latter is supplied as a plugin to illustrate how simple it is to
+extend finit with more internal inetd services.
+
+> Please note, not all UNIX daemons are prepared to run as inetd services.
+> In the example below `sshd` also need the command line argument `-i`.
+
+The inetd support in finit is quite advanced.  Not only does it launch
+services on demand, it can do so on custom ports and also filter inbound
+traffic using a poor man's [TCP wrappers][].  The syntax is very similar
+to the traditional `/etc/inetd.conf`, yet keeping with the style of
+Finit:
+
+```shell
+    # Launch SSH on demand, in runlevels 2-5 as root
+    inetd ssh/tcp            nowait [2345] @root:root /usr/sbin/sshd -i
+```
+
+A more advanced example is listed below, please note the *incompatible
+syntax change* that was made between Finit v1.12 and v1.13 to support
+deny filters:
+
+```shell
+    # Start sshd if inbound connection on eth0, port 222, or
+    # inbound on eth1, port 22.  Ignore on other interfaces.
+    inetd 222/tcp@eth0       nowait [2345] /usr/sbin/sshd -i
+    inetd ssh/tcp@eth1,eth1  nowait [2345] /usr/sbin/sshd -i
+```
+	
+If `eth0` is your Internet interface you may want to avoid using the
+default port.  To run ssh on port 222, and all others on port 22:
+    
+```shell
+    inetd 222/tcp@eth0       nowait [2345] /usr/sbin/sshd -i
+    inetd ssh/tcp@*,!eth0    nowait [2345] /usr/sbin/sshd -i
+```
+
+Compared to Finit v1.12 you must *explicitly deny* access from `eth0`!
+    
+
+**Internal Services**
+
+The original `inetd` had a few standard services built-in:
+
+- time
+- echo
+- chargen
+- discard
+
+Finit only supports the `time` service.  This is realized as a plugin to
+provide a simple means of testing the inetd functionality stand-alone,
+but also as a very rudimentary time server for rdate clients.
+
+The `time.so` inetd plugin is set up as follows.  Notice the keyword
+`internal` which applies to all built-in inetd services:
+
+```shell
+    inetd time/tcp         nowait [2345] internal
+```
+
+Then call `rdate` from a remote machine (or use localhost):
+
+```shell
+    rdate -p <IP>
+```
+
+If you use `time/udp` you must use the standard rdate implementation and
+then call it with `rdate -up` to connect using UDP.  Without the `-p`
+argument rdate will try to set the system clock.  Please note that rdate
+has been deprecated by the NTP protocol and this plugin should only be
+used for testing or environments where NTP for some reason is blocked.
+Also, remember the UNIX year 2038 bug, or in the case of RFC 868 (and
+some NTP implementations), year 2036!
+
+**Note:** There is currently no verification that the same port is used
+  more than once.  So a standard `inetd http/tcp` service will clash
+  with an ssh entry for the same port `inetd 80/tcp` …
+
+
+Hooks, Callbacks & Plugins
+--------------------------
+
+Finit provides only the bare necessities for starting and supervising
+processes, with an emphasis on *bare* — for your convenience it does
+however come with support for hooks, service callbacks and plugins that
+can used to extend finit with.
+
+### Plugins
+
+For your convenience a set of *optional* plugins are available:
+
+* *alsa-utils.so*: Restore and save ALSA sound settings on
+  startup/shutdown.
+
+* *bootmisc.so*: Setup necessary files for UTMP, tracks logins at boot.
+
+* *dbus.so*: Setup and start system message bus, D-Bus, at boot.
+
+* *hwclock.so*: Restore and save system clock from/to RTC on
+  startup/shutdown.
+
+* *initctl.so*: Extends finit with a traditional `initctl` functionality.
+
+* *netlink.so*: Listens to Linux kernel Netlink events for gateway and
+  interfaces.  These events are then sent to the Finit service monitor
+  for services that may want to be SIGHUP'ed on new default route or
+  interfaces going up/down.
+
+* *resolvconf.so*: Setup necessary files for `resolvconf` at startup.
+
+* *time.so*: RFC 868 (rdate) plugin.  Start as inetd service.  Useful
+  for testing inetd filtering — BusyBox has an rdate (TCP) client.
+
+* *tty.so*: Watches `/dev`, using inotify, for new device nodes (TTY's)
+  to start/stop getty consoles on them on demand.  Useful when plugging
+  in a usb2serial converter to login to your embedded device.
+
+* *urandom.so*: Setup random seed at startup.
+
+* *x11-common.so*: Setup necessary files for X-Window.
+
+Usually you want to hook into the boot process once, simple hook plugins
+like `bootmisc.so` are great for that purpose.  They are called at each
+hook point in the boot process, useful to insert some pre-bootstrap
+mechanisms, like generating configuration files, restoring HW device
+state, etc.  Available hook points are:
+
+### Bootstrap Hooks
+
+* `HOOK_ROOTFS_UP`: When `finit.conf` has been read and `/` has is
+  mounted — very early
+
+* `HOOK_BASEFS_UP`: All of `/etc/fstab` is mounted, swap is available
+  and default init signals are setup
+
+* `HOOK_NETWORK_UP`: System bootstrap, runlevel S, has completed and
+  networking is up (`lo` is up and the `network` script has run)
+
+* `HOOK_SVC_UP`: All services in the active runlevel has been launched
+
+* `HOOK_SYSTEM_UP`: All services *and* everything in `/etc/finit.d`
+  has been launched
+
+### Runtime Hooks
+
+* `HOOK_SVC_RECONF`: Called when the user has changed something in the
+  `/etc/finit.d` directory and issued `SIGHUP`.  The hook is called when
+  all modified/removed services have been stopped.  When the hook has
+  completed, Finit continues to start all modified and new services.
+
+* `HOOK_RUNLEVEL_CHANGE`: Called when the user has issued a runlevel
+  change.  The hook is called when services not matching the new
+  runlevel have been been stopped.  When the hook has completed, Finit
+  continues to start all services in the new runlevel.
+
+### Shutdown Hooks
+
+* `HOOK_SHUTDOWN`: Called at shutdown/reboot, right before all
+  services are sent `SIGTERM`
+
+Plugins like `initctl.so` and `tty.so` extend finit by acting on events,
+they are called I/O plugins and are called from the finit main loop when
+`poll()` detects an event.  See the source code for `plugins/*.c` for
+more help and ideas.
+
+### Callbacks
+
+Callback plugins are called by finit right before a process is started,
+or restarted if it exits.  The callback runs as a separate process and
+receives a pointer to the `svc_t` of the service, with all command line
+parameters free to modify as needed.
+
+All the callback needs to do is respond with one of: `SVC_STOP (0)`
+tells Finit to *not* start the service, `SVC_START (1)` to start the
+service, or `SVC_RELOAD (2)` to have finit signal the process with
+`SIGHUP`.
+
+
+Rebooting & Halting
+-------------------
+
+Finit handles `SIGUSR1` and `SIGUSR2` for reboot and halt, and listens
+to `/dev/initctl` so system reboot and halt commands also work.  The
+latter is implemented in the optional `initctl.so` plugin and can be
+accessed with the traditional `telinit` command line tool, symlinked to
+`finit`.  Hence, if finit is your system init, then `init q` will work
+as the UNIX beards intended.
+
+```shell
+    ~ $ telinit
+    Usage: telinit [OPTIONS] [q | Q | 0-9]
+    
+    Options:
+      -h, --help            This help text
+      -v, --version         Show Finit version
+    
+    Commands:
+      q | Q           Reload *.conf in /etc/finit.d/, like SIGHUP
+      0 - 9           Change runlevel: 0 halt, 6 reboot
+```
+
+
+Commands & Status
+-----------------
+
+Finit also implements a more modern API to query status, and start/stop
+services, called `initctl`.  Unlike `telinit` the `initctl` tool does
+not return until the given command has fully completed.
+
+```shell
+    ~ $ initctl -h
+    Usage: initctl [OPTIONS] <COMMAND>
+    
+    Options:
+      -d, --debug           Debug initctl (client)
+      -v, --verbose         Verbose output
+      -h, --help            This help text
+    
+    Commands:
+      debug                 Toggle Finit (daemon) debug
+      emit     <EV>         Emit an event.  Can be a predefined event: RELOAD, STOP,
+                            START, or a custom string to match the event list in a
+                            service stanza, e.g: GW:UP, IFUP:IFNAME, IFDN:IFNAME,
+                            where IFNAME is the interface name, e.g. eth0
+      reload                Reload *.conf in /etc/finit.d/ and activate changes
+      runlevel [0-9]        Show or set runlevel: 0 halt, 6 reboot
+      status | show         Show status of services
+      start    <JOB|NAME>   Start stopped job or service
+      stop     <JOB|NAME>   Stop/Pause running job or service
+      restart  <JOB|NAME>   Restart (stop/start) job or service
+      reload   <JOB|NAME>   Reload (SIGHUP) job or service
+      version               Show Finit version
+```
+
+The `emit <EV>` command can be used to send events to Finit.  Built-in
+events are: RELOAD, STOP, START.  These events act on a lower level than
+their command counterparts.  The `reload` command reloads all `*.conf`
+files in `/etc/finit.d/` *and* activates the changes, with `emit RELOAD`
+only the `*.conf` files are reloaded.
+
+**Note:** The `emit STOP` event is more like "prepare" than "stop".
+  Depending on how the service is declared, `<!>` or not, the service
+  may be stopped, or skipped to be be sent `SIGHUP` later when `emit
+  START` is issued.
+
+To achieve the same result as `initctl reload` emit all three events:
+
+```shell
+    ~ $ initctl emit "RELOAD,STOP,START"
+```
+
+On an embedded system this can be used when changing complete system
+configuration.   Between `STOP` and `START` reset/change any hardware
+or kernel settings required to be in effect before new services are
+started.
+
+```shell
+    # 1. Update/Change/Generate all daemon configuration files
+    ~ $ …
+    
+    # 2. Update /etc/finit.d/*.conf
+    ~ $ …
+    
+    # 3. Prepare finit, stop all old/previous services
+    ~ $ initctl emit "RELOAD,STOP"
+    
+    # 4. Reconfigure hardware, interfaces/bridges/VLANs, etc.
+    ~ $ brctl    …
+    ~ $ vconfig  …
+    ~ $ ifconfig …
+    
+    # 5. Complete finit reload by starting all new services and
+    #    SIGHUP any changed services
+    ~ $ initctl emit "START"
+```
+	
+The `emit <EV>` command can also be used to emit custom events.  In
+fact, the event is a simple string.  Declare a list of events in a
+service stanza: `service … <GW:UP,IFUP:eth0>` to reload (`SIGHUP`) a
+service when recieving the `"GW:UP"` or `"IFUP:eth0"` strings.  If a
+service cannot handle reload and must be stopped-started, simply add an
+exclamation mark first: `service … <!GW:UP,IFUP:eth0>`.
+
+The `<!>` notation to a service stanza can be used empty, then it will
+apply to `reload` and `runlevel` commands.  I.e., when a service's
+`.conf` file has been changed Finit will stop and start it instead.  If
+a service does *not* have `<!>` declared, the service will be reloaded
+(`SIGHUP`:ed) in the `START` phase instead.  The latter is the preferred
+behaviour, but not all daemons support this, unfortunately.
+
+**Note:** even though it is possible to start services not belonging to
+the current runlevel these services will not be respawned automatically
+by Finit if they exit (crash).  Hence, if the runlevel is 2, the below
+Dropbear SSH service will not be restarted if it, for some reason,
+exits.
+
+```shell
+    ~ $ initctl status -v
+    1       running  476     [S12345]   /sbin/watchdog -T 16 -t 2 -F /dev/watchdog
+    2       running  477     [S12345]   /sbin/syslogd -n -b 3 -D
+    3       running  478     [S12345]   /sbin/klogd -n
+    4:1       inetd  0       [2345]     internal time allow *:37
+    4:2       inetd  0       [2345]     internal time allow *:37
+    4:3       inetd  0       [2345]     internal 3737 allow *:3737
+    5:1       inetd  0       [2345]     /sbin/telnetd allow *:23 deny eth0,eth1
+    5:2       inetd  0       [2345]     /sbin/telnetd allow eth0:2323,eth2:2323,eth1:2323
+    6:1       inetd  0       [345]      /sbin/dropbear allow eth0:222
+    6:2       inetd  0       [345]      /sbin/dropbear allow *:22 deny eth0
+```
+
+
+Building
+--------
+
+Finit comes with a lightweight configure script to control which
+features to enable an plugins to build.  Below are a few of the main
+switches to configure:
+
+* `--prefix=`: Base prefix path for all files, except `--sbindir` and
+  `--sysconfdir`.  Used in concert with the `DESTDIR` variable.
+
+  Defaults to `/usr`.
+
+* `--sbindir=`: Path to where resulting binaries should install to. Used
+  in concert with the `DESTDIR` variable.
+
+  Defaults to `/sbin`.
+
+* `--sysconfdir=`: Path to where finit configuration files should
+  install to.  Used in concert with the `DESTDIR` variable.
+
+  Defaults to `/etc`, but is currently unused.
+
+* `--plugindir=`: Absolute path to where finit should search for
+  dynamically loadable plugins at runtime.  Can also be controlled
+  with the `--libdir` switch.
+
+  Defaults to `/lib/finit/plugins`.
+
+* `--with-plugins=`: List of stock finit plugins to build and install.
+  The build system adds `.o` or `.so` extension to the listed plugins
+  depending on the `--enable-static` switch.  Hence, list the plugins
+  *without* their extension.
+
+* `--enable-embedded`: Target finit for BusyBox getty and mdev instead
+  of a standard Linux distribution with GNU tools and udev.
+
+* `--enable-debug`: Add GDB symbols and disable code optimization.
+
+* `--enable-static`: Build Finit statically.  The plugins will be
+  built-in (.o files) instead.  Note: very untested and not all plugins
+  can be built static.  It is recommended to use `--with-plugins` and
+  select only the plugins really needed.
+
+* `--disable-inetd`: Disables the built-in inetd server.
+
+The following environment variables are checked by the makefiles and
+control what is built and where resulting binaries are installed.
+
+* `ROOTDIR=`: Top directory for building complete system, used in pretty
+  printing at build time.
+
+* `VERSION=`: Defaults to the currently released version of finit,
+  e.g., 1.3 but can be overridden by packagers using this variable to
+  add a suffix or completely alter the version.
+
+* `CFLAGS=`: Default `CFLAGS` are inherited from the environment.
+
+* `CPPFLAGS=`: Default `CPPFLAGS` are inherited from the environment.
+
+* `LDFLAGS=`: Default `LDFLAGS` are inherited from the environment.
+
+* `LDLIBS=`: Default `LIBLIBS` are inherited from the environment.
+
+* `DESTDIR=`: Used by packagers and distributions when building a
+  relocatable bundle of files.  Always prepended to the `prefix`
+  destination directory.
+
+**Example**
+
+First, unpack the archive:
+
+```shell
+    $ tar xfJ finit-1.13.tar.xz
+    $ cd finit-1.13/
+```
+
+Then configure, build and install:
+
+```shell
+    $ ./configure --with-plugins="initctl hwclock"
+    $ make
+    CC      finit.o
+    CC      conf.o
+    CC      helpers.o
+    CC      sig.o
+    CC      svc.o
+    CC      plugin.o
+    CC      strlcpy.o
+    LINK    finit
+    CC      plugins/initctl.o
+    PLUGIN  plugins/initctl.so
+    CC      plugins/hwclock.o
+    PLUGIN  plugins/hwclock.so
+	$
+    $ DESTDIR=/tmp/finit make install
+    INSTALL /tmp/finit/sbin/finit
+    INSTALL /tmp/finit/lib/finit/plugins/initctl.so
+    INSTALL /tmp/finit/lib/finit/plugins/hwclock.so
+```
+
+In this example the [finit-1.13.tar.xz][10] archive is unpacked to the
+user's home directory, configured, built and installed to a temporary
+staging directory.  The environment variable `DESTDIR` controls the
+destination directory when installing, very useful for building binary
+standalone packages.
+
+To target an embedded Linux system, usally a system that use BusyBox
+tools instead of udev & C:o, add <kbd>--enable-embedded</kbd> to the
+configure command above.
+
+For more configure flags, see <kbd>./configure --help</kbd>
+
+**Note:** If you run into problems starting Finit, take a look at
+  `finit.c`.  One of the most common problems is a custom Linux kernel
+  build that lack `CONFIG_DEVTMPFS`.  Another is too much cruft in the
+  system `/etc/fstab`.
+
+
+Running
+-------
+
+The default install does not setup finit as the system default
+`/sbin/init`, neither does it setup an initial `/etc/finit.conf`.
+
+It is assumed that users of finit are competent enough to either setup
+finit as their default `/sbin/init` or alter their respective Grub,
+LOADLIN, LILO, U-Boot/Barebox or RedBoot boot loader configuration to
+give the kernel the following extra command line:
+
+```shell
+    init=/sbin/finit
+```
+
+![Finit starting Debian 6.0](images/finit-screenshot.jpg "Finit screenshot")
+
+
+Debugging
+---------
+
+Add `finit_debug`, or `--debug`, to the kernel command line to
+enable trace messages.  A console getty is always started, see the file
+`finit.h` for more useful compile-time tweaks:
+
+```shell
+    init=/sbin/finit --debug
+```

+Goals of Finit
+==============
+
+The intent of finit is to monitor not just processes, but to supervise
+an entire system and the behavior of certain processes that declare
+themselves to be finit compliant.  Similar to launchd, the goal of
+finit is to be a replacement for:
+
+* init
+* inetd
+* crond
+* watchdogd
+
+A small and simple replacement, primarily for embedded systems, with a
+very low dependency on external packages.
+
+
+General
+-------
+
+* Add compile-time support for running `/bin/sh` instead of `getty`
+* Add `!` or `[wait <pidfile>]` to service directive to let finit pause
+  and wait for a pidfile before starting processes -- both at boot and
+  when starting processes in a runlevel.
+* Allow custom reload for processes like libreSwan's pluto
+
+        service [2345] <!gw,if:eth0,reload:'starter reload'> /sbin/pluto
+
+* Allow process callbacks to be scripts.
+* Add support for a pipe/popen where we can listen for `STOP`, `START`
+  and `RELOAD` on `STDOUT` from a script ... call it for example
+  `.monitor=` in `svc_t` ... the script named as the basename of the
+  service it monitors + `.sh`.
+* Add support for `/etc/sysctl.d`
+* Implement `initctl stop|start|restart|reload|status <SVC>` and
+  `service <SVC> stop|start|restart|reload|status` on top
+* Add PRE and POST hooks for when switching between runlevels
+* Make sure to install `queue.h` to `$(PREFIX)/include/finit/queue.h`
+* Move `finit.conf` "check" command to plugin which checks `/etc/fstab`
+  instead.  This is the de-facto practice.  But keep the check command
+  for really low-end systems w/o `/etc/fstab`.
+* Add support for generic events (strings or ubus events) that are passed
+  verbatim (?) to the service stanza definitions.
+
+
+Init
+----
+
+Finit in itself is not SysV Init compatible, it doesn't use `/etc/rc.d`
+and `/etc/inet.d` scripts to boot the system.  However, a plausible way
+to achieve compatibility would be to add a plugin to finit which reads
+`/etc/inittab` to be able to start standard Linux systems.
+
+
+Inetd
+-----
+
+Optimize interface filtering by using socket filter.  The functions
+`inet_*_peek()` and `inetd_is_allowed()` used for interace filtering
+should be possible to rewrite as socket filters.
+
+
+Crond
+-----
+
+Requirements are quite rudimentary, basic cron functionality, mainly
+system-level timed periodic tasks:
+
+* Periodically run a task, in a matching runlevel
+* Optionally run as non-root (`crontab -e` as operator)
+
+Proposed syntax:
+
+    # Crontab
+    cron @YY-mm-ddTHH:MM [LVLS] /path/to/cmd [ARGS] -- Optional descr
+    
+    # One-shot 'at' command
+    at @YY-mm-ddTHH:MM [LVLS] /path/to/cmd [ARGS] -- Optional descr
+
+Notice the ISO date in notation.  The runlevels is extra filtering
+sugar.  E.g., if cron service is only allowed in runlevels two or three
+it will not start if system currently is in runlevel four.
+
+To run a command as another user the `.conf` file must have a that
+owner.  E.g., `/etc/finit.d/extra.conf` may be owned by operator and
+only hold `cron ...` lines.
+
+What would be extremely useful is if `initctl`, or a homegrown `at`,
+could support the basic functionality of the `at` command directly from
+the shell -- that way setting up one-time jobs would not entail
+re-reading `/etc/finit.conf`
+
+
+Watchdog
+--------
+
+Support for monitoring the health of the system and its processes.
+
+* Add support for a `/dev/watchdog` built-in to replace both the BusyBox
+  watchdogd and my own refreshed uClinux-dist adaptation,
+  [watchdogd](https://github.com/troglobit/watchdogd)
+* Add a system supervisor (pmon) to optionally reboot the system when a
+  process stops responding, or when a respawn limit has been reached, as
+  well as when system load gets too high.  For details on UNIX loadavg,
+  see http://stackoverflow.com/questions/11987495/linux-proc-loadavg
+  - Default to 0.7 as MAX recommended load before warning and 0.9 reboot
+* API for processes to register with the watchdog, libwdt
+  - Deeper monitoring of a process' main loop by instrumenting
+  - If a process is not heard from within its subscribed period time
+    reboot system or restart process.
+  - Add client libwdt library, inspired by old Westermo API and the
+    [libwdt] API published in the [Fritz!Box source dump], take for
+    instance the `fritzbox7170-source-files-04.87-tar.gz` drop and see
+    the `GPL-release_kernel.tgz` in `drivers/char/avm_new/` for the
+    kernel driver, and the `LGPL-GPL-release_target_tools.tgz` in `wdt/`
+    for the userland API.
+  - When a client process (a standard app/daemon instrumented with
+    libwdt calls in its main loop) registers with the watchdog, we raise
+    the RT priority to 98 (just below the kernel watchdog in prio).
+    This to ensure that system monitoring goes before anything else in
+    the system.
+  - Use UNIX domain sockets for communication between daemon and clients
+* Separate `/etc/watchdog.conf` configuration file, or a perhaps
+  support for a more generic `/etc/finit.d/PLUGIN.conf`?
+* Support enable/disable watchdog features:
+  - Supervise processes,
+  - CPU loadavg,
+  - Watch for file descriptor leaks,
+  - etc.
+
+
+Documentation
+-------------
+
+* Write man pages for finit and `finit.conf`, steal from the excellent
+  `pimd` man pages ...
+* Update Debian `finit.conf` example with runlevels, `tty/console` and
+  dependency handling for Debian 8 (the dreaded systemd release).
+
+
+Investigation
+-------------
+
+* [FHS changes](http://askubuntu.com/questions/57297/why-has-var-run-been-migrated-to-run)
+  affecting runtime status, plugins, etc.

-Changelog from the original Eeepc fastinit:
-
-- Use mknod() instead of close(open()) call to create empty file
-- Fix random seed initialization
-- Don't try to handle signal 0, SIGKILL or SIGSTOP
-- Implement makepath() to avoid system("mkdir -p")
-- Omit first hwclock if user has CONFIG_RTC_HCTOSYS in kernel (by Metalshark)
-- Add –directisa to hwclock if user has disabled CONFIG_GENRTC and enabled
-  CONFIG_RTC but not CONFIG_HPET_TIMER and CONFIG_HPET_RTC_IRQ (by Metalshark)
-- Drop system() call to clean /tmp, it's a fresh mounted tmpfs
-- Set loopback interface using direct calls instead of system("ifconfig")
-- Copy 4096 data block in C instead of system("cat") or system("dd")
-- Draw shutdown splash screen using C calls instead of system("echo;cat")
-- Change poweroff method to reboot(RB_POWER_OFF) (by Metalshark)
-- Mount /var/run and /var/lock as tmpfs
-- Use SIG_IGN instead of empty signal handler (by Metalshark)
-- Add built-in run-parts option to be used instead of system("run-parts")
-- Reuse cmdline buffer as hostname and filename buffers
-- Open terminal in vt2 using openvt

+ * This file defines five types of data structures: singly-linked lists, 
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+ * @username: Optional username to run service as, or %NULL to run as root
+ *
+ * This function is used to register commands to be run on different
+ * system runlevels with optional username.  The @type argument details
+ * if it's service to bo monitored/respawned (daemon), a one-shot task
+ * or a command that must run in sequence and not in parallell, like
+ * service and task commands do.
+ *
+ * The @line can optionally start with a username, denoted by an @
+ * character. Like this:
+ *
+ *     service @username [!0-6,S] <!EV> /path/to/daemon arg -- Description
+ *     task @username [!0-6,S] /path/to/task arg            -- Description
+ *     run  @username [!0-6,S] /path/to/cmd arg             -- Description
+ *     inetd tcp/ssh nowait [2345] @root:root /sbin/sshd -i -- Description
+ *
+ * If the username is left out the command is started as root.  The []
+ * brackets denote the allowed runlevels, if left out the default for a
+ * service is set to [2-5].  Allowed runlevels mimic that of SysV init
+ * with the addition of the 'S' runlevel, which is only run once at
+ * startup.  It can be seen as the system bootstrap.  If a task or run
+ * command is listed in more than the [S] runlevel they will be called
+ * when changing runlevel.
+ *
+ * Services (daemons, not inetd services) also support an optional <!EV>
+ * argument.  This is for services that, e.g., require a system gateway
+ * or interface to be up before they are started.  Or restarted, or even
+ * SIGHUP'ed, when the gateway changes or interfaces come and go.  The
+ * special case when a service is declared with <!> means it does not
+ * support SIGHUP but must be STOP/START'ed at system reconfiguration.
+ *
+ * Supported service events are: GW, IFUP[:ifname], IFDN[:ifname], where
+ * the interface name (:ifname) is optional.  Actully, the check with a
+ * service event declaration is string based, so 'IFUP:ppp' will match
+ * any of "IFUP:ppp0" or "IFUP:pppoe1" sent by the netlink.so plugin.
+ *
+ * For multiple instances of the same command, e.g. multiple DHCP
+ * clients, the user must enter an ID, using the :ID syntax.
+ *
+ *     service :1 /sbin/udhcpc -i eth1
+ *     service :2 /sbin/udhcpc -i eth2
+ *
+ * Without the :ID syntax Finit will overwrite the first service line
+ * with the contents of the second.  The :ID must be [1,MAXINT].
