+This release became v4.0, and not v3.2, because of incompatible changes
+to service conditions.  There are other significant changes as well, so
+make sure to read the whole changelog when upgrading.

 ### Changes
+* The stand-alone `reboot` tool has been replaced with a symlink to
+  `initctl`, like its siblings: halt, shutdown, poweroff, and suspend.
+  Calling `reboot` & C:o now defaults to the corresponding `initctl cmd`
+  with a fallback to sending signals as per traditional SysV init.  The
+  `-f` (force) flag remains, where `reboot(2)` is called directly
 * Introducing Finit progress 𝓜𝓸𝓭𝓮𝓻𝓷
+* Removed built-in inetd super server.  If you need this functionality,
+  use an external inetd, like xinetd, instead.  A pull request for a
+  stand-alone inetd, like watchdogd and getty, is most welcome!
+* Incompatible `configure` script changes, i.e., you must give proper
+  path arguments to the script, no more guessing just GNU defaults.
+  There are examples in the documentation and the `contrib/` section
+* Change service conditions from the non-obvious `<svc/path/to/foo>` to
+  `<pid/foo:id>`.  This to hopefully make it clear that one service's
+  'pid:!foo' pidfile is another service's `<pid/foo>` condition
+* Initial support for cgroups, every service now runs in its own cgroup
+  https://twitter.com/b0rk/status/1214341831049252870?s=20
+* Major refactor of Finit's `main()` function to be able to start the
+  event loop earlier.  This also facilitated factoring out functionality
+  previously hard-coded in Finit, e.g., starting the bundled watchdogd,
+  various distro packed udevd and other hotplugging tools
 * Support for `sysv` start/stop scripts as well as monitoring forking
  services, stared using `sysv` or `service` stanza
 * Support for custom `kill:DELAY`, default 3 sec.

 * Drop `--enable-rw-roots` configure option, use `rw` for your `/`

-* Make `:ID` optional for real, use NULL/zero internally and only
-  force :ID (numbered) for inetd services, this allows ...
+* Make `:ID` optional, use NULL/zero internally this allows ...
 * Handle use-cases where multiple services share the same PID filem
  and thus the same condition path, e.g. different instances for
  different runlevels.  Allow custom condition path with `name:foo`
  syntax, creates conditions w/o a path, and ...
 * Always append `:ID` qualifier to conditions if set for a service
+* The IPC socket has moved from `/run/finit.sock` to `/run/finit/socket`
+  officially only supported for use by the `initctl` tool
+* Improved support for modern `/etc/network/interfaces`, which has
+  include statements.  No more native `ifup` of individual interfaces,
+  Finit now calls `ifup -a`, or `ifdown -a`, delegating all details to
+  the operating system.  Also, this is now done in the background, by
+  popular request

 ### Fixes

 * Fix #96: Start udevd as a proper service
 * Ensure we track run commands as well as task/service, once per runlevel
-* Fix #98: FTBFS with `--disable-inetd`
-* Make sure to unblock UDP inetd services when connection terminates.
-  Regression introduced in v3.1
 * Ensure run/tasks also go to stopping state on exit, like services,
  otherwise it is unnecessarily hard to restart them
-* Fix #99: Do not try to `SIGKILL` inetd services, they are not backed
-  by a PID.  This caused a use after free issue crashing finit.  Found

 Some components are optional: runlevel(s), condition(s) and description,
 making it easy to create simple start scripts and still possible for more
 advanced uses as well:

-    service /usr/sbin/sshd -D
+    service sshd -D

 Dependencies are handled using [conditions](doc/conditions.md).  One of
 the most common conditions is to wait for basic networking to become
 available:

+    service <net/route/default> nginx -- High performace HTTP server

 Here is another example where we instruct Finit to not start BusyBox
 `ntpd` until `syslogd` has started properly.  Finit waits for `syslogd`
 to create its PID file, by default `/var/run/syslogd.pid`.

 Traditionally, rebooting and halting a UNIX system is done by changing
 its runlevel.  Finit comes with its own tooling providing: `shutdown`,
-`reboot`, `poweroff`, and `suspend`, but also the traditional `init` and
-`telinit`, as well as a more modern `initctl` tool, detailed in the next
-section.
+`reboot`, `poweroff`, and `suspend`, but also the `initctl` tool,
+detailed in the next section.

 For compatibility reasons Finit listens to the same set of signals as
 BusyBox init.  This is not 100% compatible with SysV init, but clearly
 the more common combination for Finit.  For more details, see
 [doc/signals.md](doc/signals.md).

-Finit also listens to the classic SysV init FIFO, used by `telinit`.
-Support for this is implemented by the `initctl.so` plugin.  Hence,
-`telinit q` will work as the UNIX beards intended.

-```shell
-~ # telinit -h
-Usage: telinit [OPTIONS] [q | Q | 0-9]

-Options:
-  -h, --help      This help text
-  -V, --version   Show Finit version

-Commands:
-  0               Power-off the system, same as initctl poweroff
-  6               Reboot the system, same as initctl reboot
-  2, 3, 4, 5      Change runlevel. Starts services in new runlevel, stops any

 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:
+Initially Finit aimed to be more than a processes monitor, acting as a
+replacement for cron/at and inetd as well.  Over time, however, the true
+value in the project turned out to be:

-* init
-* inetd
-* crond
-* watchdogd
-
-A small and simple replacement, primarily for embedded systems, with a
-low dependency on external packages.  A compliant software is one that
-can run as a damon in the foreground.  If it can also touch its PID file
-after a reconfiguration (`initctl reload`), the Finit dependency system
-can also be used.
+> A simple SysV init and systemd replacement, primarily for embedded
+> systems, container, and dedicated server applications.


-Near Future
-----------
+Misc TODOs
+----------

+Some of these are also registered in the issue tracker on GitHub.
+
+* Refactor the .conf parser, parse user input in a separate process
+* Move process monitor to separate process (same as parser?)
+* Add new (complimentary) .svc file format to slowly migrate away
+  from the very terse one-liner format currently used
+* Allow running as non-pid1 => read .conf and RCSD form cmdline
 * When a process dies, and Finit does not restart it, we should collect
  a `siginfo_t` from the SIGCHLD signal and supply to the user in case
  `initctl status <process>` is called to debug the issue.
-* Merge UDP redirect service uredir as an UDP inetd variant
 * Add `finit.conf` support for UPS notification (SIGPWR) to start a task
  using, e.g. <sys/power/{ok,fail,low}> conditions.  More info in sig.c
 * Add `finit.conf` support for ctrl-alt-delete (SIGINT) and kbrequest,
  i.e. KeyboardSignal, (SIGWINCH) behavior.  Using conditions to a task,
  e.g, <sys/key/ctrlaltdel> and <sys/key/signal> like SIGPWR handling.
-* Cron/At support, see below
 * Write man pages for finit and `finit.conf`, steal from the excellent
  `pimd` man pages ...
-
-
-General
-------
-
-* Add support for timed shutdown in Finit, including cancelled shutdown,
-  possibly using an at-job, see [crond section](#Crond) below
+* Add support for timed shutdown in Finit, including cancelled shutdown
 * Add support for JSON output, or similar, from `initctl show`, e.g.
  `initctl show --json`
-* [Solaris SMF][] (Service Management Facility) has some interesting
-  features that may be well worth looking into adopting:
-  
-         svcs enable -rt svc:/network/ssh:default
-  
-  That is: (r)esolve dependencies and only enable ssh (t)emporary
-  in the default runlevel when networking is available.
-* `initctl add /sbin/service -n -- Service description`, for details
-  see above [Solaris SMF][] featuer, issue #55 and issue #69,
-  https://github.com/troglobit/finit/issues/69#issuecomment-287907610
-* Changing the name of a pidfile, `pid:[/path/]file.pid`, after a
-  service has been started is not supported atm.  The previous name will
-  not be (never) removed and the new name will not be created until the
-  process has been stopped and started again.
-* PID files created in subdirectories to `/run` is not supported right
-  now inotify listeners should be automatically created (and removed)
-  when a subdirectory is added (or removed).

 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
+and `/etc/init.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
-----
-
-* Add support for throttling connections.
-* 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.
-* Optimize HTTP/HTTPS inetd connections by adding basic support for the
-  `inetd` variant `redir http/tcp@eth0 nowait [2345] 127.0.0.1:8080`,
-  which would reduce the overhead of spawn the web server on each HTTP
-  connection, yet still provide a means of filtering access per iface.
-
-
-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 @SPEC [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 the `at` notation.  The `cron @SPEC` could use
-are mo loose notation, e.g. `@hourly`, `@midnight`, `@daily`, `@weekly`,
-`@reboot`, etc.  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`

+Finit comes with a `pidfile` and `netlink` plugin.  When enabled, the

 With the example listed above, finit does not start the `/sbin/netd`
 daemon until `setupd` and `zebra` has started *and* created their PID
 files.  Which they do when they have completed their initial set up and
 are ready to receive signals.

+Finit supports sourcing environment variables from `/etc/default/*`, or

+scripts, where the start-stop script is a generic script for the given
+service, `foo`, and the options for the service are sourced from the

+
+* `/etc/default/foo`:
+
+        FOO_OPTIONS=--extra-arg="bar" -s -x

+

+
+### Services
+
+**Syntax:** `service [LVLS] <COND> /path/to/daemon ARGS -- Optional description`
+
+Service, or daemon, to be monitored and automatically restarted if it
+exits prematurely.  Finit tries to restart services that die 10 times
+before giving up, then you have to `initctl restart NAME` it manually.
  
-* `service [LVLS] <COND> /path/to/daemon ARGS -- Optional description`  
-  Service, or daemon, to be monitored and automatically restarted if it
-  exits prematurely.
+For daemons that support it, we recommend appending `--foreground`,
+`--no-background`, `-n`, `-F`, or similar command line argument to
+prevent them from forking off a sub-process in the background.  This is
+the most reliable way to monitor a service.
+
+However, not all daemons support running in the foreground, or they may
+start logging to the foreground as well, these are called forking
+services and are supported using the same syntax as forking `sysv`
+services, using the `pid:!/path/to/pidfile.pid` syntax.
  
-  For daemons that support it, we recommend appending `--foreground`, or
-  `--no-background`, argument to prevent them from forking off a
-  sub-process in the background.  This is the most reliable way to
-  monitor a service.
+**Example:**

-  However, not all daemons support running in the foreground, or they
-  may start logging to the foreground as well, these are called forking
-  services and are supported using the same syntax as forking `sysv`
-  services, using the `pid:!/path/to/pidfile.pid` syntax.
+In the case of `ospfd` (below), we omit the `-d` flag (daemonize) to
+prevent it from forking to the background:
+
+    service [2345] <pid/zebra> /sbin/ospfd -- OSPF daemon
+
+`[2345]` denote the runlevels `ospfd` is allowed to run in, they are
+optional and default to level 2-5 if omitted.
  
-  In the case of `ospfd` (below), we omit the `-d` flag to prevent it
-  from forking (daemonizing):
+`<...>` is the condition for starting `ospfd`.  In this example Finit
+waits for another service, `zebra`, to have created its PID file in
+`/var/run/quagga/zebra.pid` before starting `ospfd`.  Finit watches
+*all* files in `/var/run`, for each file named `*.pid`, or `*/pid`,
+Finit opens it and find the matching `NAME:ID` using the PID.

-```shell
-        service [2345] <svc/sbin/zebra> /sbin/ospfd -- OSPF daemon
-```
+Some services do not maintain a PID file and rather than patching each
+application Finit provides a workaround.  A `pid` keyword can be set
+to have Finit automatically create (when starting) and later remove
+(when stopping) the PID file.  The file is created in the `/var/run`
+directory using the `basename(1)` of the service.  The default can be
+modified with an optional `pid:`-argument:

-  The `[2345]` is the runlevels `ospfd` is allowed to run in, they are
-  optional and default to level 2-5 if left out.
-  
-  The `<...>` is the condition for starting `ospfd`.  In this example
-  Finit waits for another service, `/sbin/zebra`, to have created its
-  PID file in `/var/run/zebra.pid` before starting `ospfd`.

-  (when stopping) the PID file.  The file is created in the `/var/run`

-  modified with an optional argument:
+For example, by adding `pid:/run/foo.pid` to the service `/sbin/bar`,
+that PID file will, not only be created and removed automatically, but
+also be used by the Finit condition subsystem.  So a service/run/task
+can depend on `<pid/bar>`.

-        pid[:[/path/to/]filename[.pid]]
+>  For a detailed description of conditions, and how to debug them,
+>  see the [Finit Conditions](conditions.md) document.

-  For example, by adding `pid:/run/foo.pid` to the service `/sbin/bar`
-  that PID file will, not only be created and removed automatically, but
-  also be used by the Finit condition subsystem.  So a service/run/task
-  can depend on `<svc/sbin/foo>`, notice the composition of conditions.
+If a service should not be automatically started, it can be configured
+as manual with the optional `manual` argument. The service can then be
+started at any time by running `initctl start <service>`.

-  However, if a service `bar` *does* create a PID file, using `foo.pid`,
-  we can inform Finit of this by prepending an `!`:
+    manual:yes

-        pid:!/run/foo.pid
+The name of a service, shown by the `initctl` tool, defaults to the
+basename of the service executable. It can be changed with the
+optional `name` argument:

-  Here Finit will *not* create/remove/touch the PID file, only use it
-  for the condition handling instead of the default PID file name.
+    name:<service-name>

->  For a detailed description of conditions, and how to debug them, see
->  the [Finit Conditions](conditions.md) document.
+When stopping a service (run/task/sysv/service), either manually or
+when moving to another runlevel, Finit starts by sending `SIGTERM`, to
+allow the process to shut down gracefully.  If the process has not
+been collected within 3 seconds, Finit sends `SIGKILL`.  To halt the
+process using a different signal, use the option `halt:SIGNAL`, e.g.,
+`halt:SIGPWR`.  To change the delay between your halt signal and KILL,
+use the option `kill:SEC`, e.g., `kill:10` to wait 10 seconds before
+sending `SIGKILL`.

-  If a service should not be automatically started, it can be configured
-  as manual with the optional `manual` argument. The service can then be
-  started at any time by running `initctl start <service>`.

-        manual:yes
+### Run-parts Scripts

-  The name of a service, shown by the `initctl` tool, defaults to the
-  basename of the service executable. It can be changed with the
-  optional `name` argument:
+**Syntax:** `runparts <DIR>`

-        name:<service-name>
+Call [run-parts(8)][] on `DIR` to run start scripts.  All executable
+files, or scripts, in the directory are called, in alphabetic order.
+The scripts in this directory are executed at the very end of runlevel
+`S`, bootstrap.

-  When stopping a service (run/task/sysv/service), either manually or
-  when moving to another runlevel, Finit starts by sending `SIGTERM`, to
-  allow the process to shut down gracefully.  If the process has not
-  been collected within 3 seconds, Finit sends `SIGKILL`.  To halt the
-  process using a different signal, use the option `halt:SIGNAL`, e.g.,
-  `halt:SIGPWR`.  To change the delay between your halt signal and KILL,
-  use the option `kill:SEC`, e.g., `kill:10` to wait 10 seconds before
-  sending `SIGKILL`.
+It can be beneficial to use `S01name`, `S02othername`, etc. if there
+is a dependency order between the scripts.  Symlinks to existing
+daemons can talso be used, but make sure they daemonize by default.

-* `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.
+Similar to the `/etc/rc.local` shell script, make sure that all your
+services and programs either terminate or start in the background or
+you will block Finit.

-```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`:
+### Including Finit Configs

-```shell
-        inetd 2323/tcp@eth0 nowait [2345] /sbin/telnetd -i -F
-```
+**Syntax:** `include <CONF>`

-  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.
+Include another configuration file.  Absolute path required.

-  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 `DIR` to run start scripts.  All executable
-  files, or scripts, in the directory are called, in alphabetic order.
-  The scripts in this directory are executed at the very end of runlevel
-  `S`, bootstrap.
+### General Logging

-  It can be beneficial to use `S01name`, `S02othername`, etc. if there
-  is a dependency order between the scripts.  Symlinks to existing
-  daemons can talso be used, but make sure they daemonize by default.
+**Syntax:** `log size:200k count:5`

-* `log size:200k count:5`
+The count value is recommended to be between 1-5, with a default 5.

-Internet Super Server
-=====================

-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.  Today more built-in
-services are available.
-
-> 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`!

-To protect against looping attacks, the inetd server will refuse UDP
-service if the reply port corresponds to any internal service.  Similar
-to how the FreeBSD inetd operates.
-
-
-**Internal Services**
-
-Like the original `inetd`, Finit has a few standard services built-in.
-They are realized as plugins to provide a simple means of testing the
-inetd functionality stand-alone.  But this also provides both a useful
-network testing/availability, as well as a rudimentary time server for
-`rdate` clients.
-
- echo
- chargen
- daytime
- discard
- time
-
-For security reasons they are all disabled by default and have to be
-enabled with both the `configure` script and a special `inetd` stanza in
-the `finit.conf` or `finit.d/*.conf` like this:
-
-```shell
-    inetd echo/udp           wait [2345] internal
-    inetd echo/tcp         nowait [2345] internal
-    inetd chargen/udp        wait [2345] internal
-    inetd chargen/tcp      nowait [2345] internal
-    inetd daytime/udp        wait [2345] internal
-    inetd daytime/tcp      nowait [2345] internal
-    inetd discard/udp        wait [2345] internal
-    inetd discard/tcp      nowait [2345] internal
-    inetd time/udp           wait [2345] internal
-    inetd time/tcp         nowait [2345] internal
-```
-
-Then call `rdate` from a remote machine (or use localhost):
-
-```shell
-    rdate -p  <IP>
-    rdate -up <IP>
-```
-
-Or `echoping` to reach the echo service:
-
-```shell
-    echoping -v  <IP>
-    echoping -uv <IP>
-```
-
-Or `echoping -d` to reach the discard service:
-
-```shell
-    echoping -dv  <IP>
-    echoping -duv <IP>
-```
-
-Or `echoping -c` to reach the chargen service:
-
-```shell
-    echoping -cv  <IP>
-    echoping -cuv <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` …
