+Change Log
+==========
+
+All notable changes to the project are documented in this file.
+
+
+[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
+* Remove finit.h from svc.h, plugins should not need this.
+* Move utility macros etc. to helpers.h
+* Make `finit.h` daemon internal, only
+* Move defines of FIFO, conf and rcS.d to Makefile => correct paths
+* Add support for installing required headers in system include dir
+* Better support for distributions and packagers with install-exec,
+  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 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 an `inetd` server built-in.  No need to maintain a
+separate config file for services that you want to start on demand.
+
+**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 either *boot hooks* into different stages of the
+boot process, *service callbacks*, or *pure extensions*.  A plugin is a
+C file that compiles 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.  See examples in the `plugins/` directory.
+
+Plugin capabilities:
+
+* Service callbacks -- modify service arguments, run/restart/stop
+* Task/Run callbacks -- a one-shot commands, executed in sequence
+* Hooks -- hook into the boot at predefined points to extend finit
+* I/O -- listen to external events and control finit behavior/services
+
+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 to the background.
+
+* `inetd SVC[@iface[:port]]/PROTO <wait|nowait> [LVLS] /path/to/daemon args`
+
+  Launch daemon on demand when a client initiates a connection to `SVC`.
+  Services (SVC) are specified in the standard UNIX `/etc/services`
+  file.  With optional filtering for `iface` and possible custom `port`.
+  The following example opens port 2323 and only allows inbound telnet
+  connections from `eth0`:
+
+    inetd telnet@eth0:2323/tcp nowait [2345] /sbin/telnetd -i -F
+
+  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.
+
+* `runparts <PATH>`
+
+  Call run-parts(8) on a directory other than default ``/etc/finit.d``
+
+* `include <CONF>`
+
+  Include another configuration file, ``/etc/finit.d``, or runparts path
+  is prepended to file if the file is not found or an absolute path is
+  not given
+
+* `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:
+
+    run [2345] @joe:users /usr/bin/logger "Hello world"
+
+
+/etc/finit.d
+------------
+
+At the end of the boot, when networking and all services are up, finit
+calls its built-in [run-parts(8)] on the `/etc/finit.d/` 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. Setup `/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. Setup `/etc/sysctl.conf`
+12. Setup hostname and loopback
+13. Call `network` script, if set in `/etc/finit.conf`
+14. Call 3rd level hooks, `HOOK_NETWORK_UP`
+15. Switch to active runlevel, as set in `/etc/finit.conf`, default 2.
+    Here is where the rest of all tasks and inetd services are started.
+16. Call 4th level hooks, `HOOK_SVC_UP`
+17. Run-parts in `/etc/finit.d`, if any
+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.
+
+To specify an allowed set of runlevels for a `service`, `run` command, `task`,
+or `tty`, add `[NNN]` to it in your `/etc/finit.conf`, like this:
+
+    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.
+
+
+Inetd
+-----
+
+A built-in *Internet Super Server* support was added in Finit v1.12,
+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 tcpwrappers.  The syntax is very similar to
+traditional `/etc/inetd.conf`, yet keeping with the style of Finit:
+
+    # 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:
+
+    # Start sshd if inbound connection on eth0, port 222, or
+    # inbound on eth1, port 22.  Ignore on other interfaces.
+    inetd ssh@eth0:222/tcp nowait [2345] /usr/sbin/sshd -i
+    inetd ssh@eth1:22/tcp  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:
+    
+    inetd ssh@eth0:222/tcp nowait [2345] /usr/sbin/sshd -i
+    inetd ssh/tcp          nowait [2345] /usr/sbin/sshd -i
+    
+This actually adds a deny rule for eth0 on ssh/tcp, implicitly.  You can
+even list the services in the reverse order with the same result:
+    
+    inetd ssh/tcp          nowait [2345] /usr/sbin/sshd -i
+    inetd ssh@eth0:222/tcp nowait [2345] /usr/sbin/sshd -i
+    
+There is no specific deny syntax available yet, see the TODO file for
+more details on how this can be implemented.
+
+The `time.so` inetd plugin setup as follows.  Notice the keyword
+`internal` which applies to all built-in inetd services:
+
+    inetd time/tcp         nowait [2345] internal
+
+Then call `rdate` from a remote machine (or use localhost):
+
+    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!
+
+
+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.  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.
+
+* *resolvconf.so*: Setup necessary files for resolvconf at startup.
+
+* *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.
+
+* *time.so*: RFC 868 (rdate) plugin.  Start as inetd service.  Useful
+  for testing inetd filtering -- BusyBox has an rdate (TCP) client.
+
+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:
+
+* `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
+
+* `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.
+
+Callback plugins are called by finit them right before a process is
+started, or restarted if it exits.  The callback receive a pointer to
+the `svc_t` (defined in `svc.h`) of the service, with all command line
+parameters free to modify if 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 should also work.
+This latter functionality is implemented in the optional `initctl.so`
+plugin.
+
+
+Building
+--------
+
+The finit build system does not employ the GNU Configure and Build System,
+instead standard makefiles are used. The user is encouraged to make source
+code changes, using defines and conditionally building plugins instead to
+alter the behavior of finit.
+
+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.
+
+* `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.
+
+* `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.
+
+* `PLUGINS=`: List of stock finit plugins to build and install.
+
+* `plugindir=`: Absolute path to where finit should look for dynamically
+  loadable plugins at runtime.  At installation prepended by `DESTDIR`
+  and `prefix`.
+
+  Defaults to `/lib/finit/plugins`.
+
+* `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:
+
+<kbd>$ tar xfJ finit-1.3.tar.xz; cd finit-1.3/</kbd>
+
+Then build and install:
+
+<kbd>$ PLUGINS="initctl.so hwclock.so" DESTDIR=/tmp/finit make install</kbd>
+
+      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
+      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-1.3.tar.xz][10] archive is unpacked to the
+user's home directory, built and installed to a temporary staging
+directory.  The environment variables `DESTDIR` and `PLUGINS` are
+changed to suit this particular build.
+
+
+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:
+
+    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:
+
+    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 supoprt for running `/bin/sh` instead of `getty`
+* Add support for `init <q | reload-configuration>` and `SIGHUP` to
+  have finit reload its `finit.conf`, but also
+* Add support for inotify to automatically reload `finit.conf`
+* 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
+* Add support for `init -v,--version | version`
+* Cleanup move sources from top-level directory to `src/` and `include/`
+* 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`.
+
+
+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
+-----
+
+Simple way of running Internet services on demand, like the old inetd:
+
+    inetd PORT/PROTO <wait|nowait> [@USER[:GROUP]] /path/to/daemon args -- desc
+
+Examples:
+
+    # Inetd services, launched on demand
+    inetd ssh/tcp nowait [2345] @root:root /usr/sbin/sshd -i -- SSH daemon
+
+In keeping with the finit tradition, an optional callback can be setup
+to each inetd service.  When a client connects the finit will call the
+callback with a `struct in_pktinfo` argument which the callback then can
+allowed or deny.
+
+Alternatively, borrowing slightly from TCP wrappers by Wietse Venema, a
+set of `allow` and `deny` directives can be added to `finit.conf` to
+control inetd services.  It could be what IP addreses, networks or
+interfaces are allowed to connect to the given inetd services.  To start
+with the easiest (and what we need for WeOS at Westermo) is allow/deny
+per iface.
+
+    # Disable access to SSH
+    deny  ssh all
+    # Allow SSH connections originating from eth0
+    allow ssh eth0
+
+Another option, to further extend the Inetd capabilities, is a separate
+`finetd.conf` to list services.  This would be beneficial when running
+an SSH service on different ports on different interfaces:
+
+    # Run SSH on port 22 on all interfaces except upstream
+    tcp ssh {
+       listen = *, !wan0
+       exec   = dropbear -i
+    }
+    
+    # Run SSH on non-standard port 222 for upstream interface
+    tcp ssh {
+       port   = 222
+       listen = wan0
+       exec   = dropbear -i
+       wait   = yes
+    }
+    
+    # Run TFTP service on all interfaces except upstream interface
+    udp tftp {
+       listen = *, !wan0
+       exec   = uftpd -i -t
+       user   = root
+    }
+
+or, more concise
+
+    # System has four interfaces: wan0, eth0, eth1, eth2
+    # This runs SSH on only three, with various ports
+    tcp ssh {
+       listen = wan0:222 eth0:22 eth1:22
+       exec   = /usr/sbin/dropbear -i
+       wait   = yes
+    }
+
+this would be equivalent
+
+    tcp ssh {
+       listen = wan0:222 !eth2
+       exec   = /usr/sbin/dropbear -i
+       wait   = yes
+    }
+
+Syntax similar to [xinetd](http://en.wikipedia.org/wiki/Xinetd)
+
+### Custom Inet Port for Common Services
+
+- How to do this, without an obtrusive syntax?
+
+Maybe like this?  Then we can still refer to it as the time protocol,
+and have multiple entries.
+
+    inetd time:8037/udp wait [2345] @root:root internal
+    inetd time:3737/udp wait [2345] @root:root internal
+
+But what if we want to have different allow/deny rules per service?
+Here's a proposal, similar to user/pass encoding in URI's.  This variant
+could potentially be a lot easier to implement and also to maintain for
+users, compared to the above allow/deny/xinetd variants.
+
+    inetd ssh@eth0:222/tcp nowait [2345] /usr/sbin/sshd -i
+    inetd ssh@eth1:22/tcp  nowait [2345] /usr/sbin/sshd -i
+
+or
+
+    inetd ssh@eth0:222/tcp nowait [2345] /usr/sbin/sshd -i
+    inetd ssh@*:22/tcp     nowait [2345] /usr/sbin/sshd -i
+
+or
+
+    inetd ssh@eth0:222/tcp nowait [2345] /usr/sbin/sshd -i
+    inetd ssh/tcp          nowait [2345] /usr/sbin/sshd -i
+
+All three versions would be equivalent, except for the first one when
+there are more interfaces than just eth0 and eth1.  The latter two would
+however be equivalent.
+
+Multiple `inetd ssh` entries with the same port will not be unique, they
+will reuse all settings of the first listed entry.  However, an entry
+with a unique port and interface will be registered as a unique service.
+
+**Note:** Also, there is currently no verification that the same port is
+  used more than once.  So a standard http service will clash with an
+  ssh entry ssh@*:80/tcp ... why you would ever want that?
+
+Inetd callbacks are no different from other callbacks.  They match to an
+inetd line using the command.  So multiple `/usr/bin/sshd` inetd lines
+in `finit.conf` will all use the same callback.  However, the callback
+will be called with the Internet port and interface as arguments.  Like
+this:
+
+    svc_cmd_t sshd_callback(svc_t *svc, int port, char *ifname)
+    {
+        if (!cfg_is_ssh_enabled(ifname, port))
+            return SVC_STOP;
+    
+        return SVC_START;
+    }
+
+As usual, the callback is run in a separate process context and it is up
+to the implementer to return `SVC_STOP` or `SVC_START` (`SVC_RELOAD` is
+not applicable for inetd services).
+
+
+### Internal inetd services
+
+There are a few standard services that inetd usually had built-in:
+
+- time
+- echo
+- chargen
+- discard
+
+At least 'time' will be implemented in finit, as a plugin, to serve as a
+simple means of testing inetd functionality stand-alone, but also as a
+very rudimentary time server for rdate clients.
+
+Example:
+
+    # Built-in inetd time service, launched on demand
+    inetd time/udp wait [2345] @root:root internal
+
+
+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.
