-[4.1][UNRELEASED]
------------------
+[4.2][] - 2022-01-16
+--------------------
+
+### Changes
+* Support for non-root users to use `initctl`, e.g. group wheel
+* Support for new libite (-lite) header namespace
+* RTC plugin now reset an invalid RTC time to the kernel default
+  time, 2000-01-01 00:00, prevents errors and is less crazy than
+  some systems coming with with <= Jan 1, 1970
+* urandom plugin now use RNDADDENTROPY ioctl to seed kernel rng,
+  incrementing entropy count.  Also, 32 kiB instead of 512 bytes are
+  now saved (and restored) on reboot.  This should greatly improve
+  reliability of systems with none or poor HWRNG
+* Kernel logging to console (loglevel >= 7, debug, when quiet mode is
+  not used) is now honored by Finit, regardless of the finit.debug
+  command line option
+* Reduced default log level from `LOG_NOTICE` to `LOG_INFO`
+* Wrapped all calls to mount(2) to add logging in case of failure
+* New configure options to control fastboot (no fsck) and fsck fix
+  options, by Ming Liu, Atlas Copco
+* Support for overriding default `/etc/nologin` file with an external
+  `#define`, by Ming Liu, Atlas Copco
+* Support for overriding default `/var/run/dbus/pid` file with an
+  external `#define`, by Ming Liu, Atlas Copco
+* Support for more service options to control respawn behavior of
+  crashing services, by Robert Andersson and Ming Liu, Atlas Copco
+* Support for `initctl ident [NAME]` which lists all instances of
+  `NAME`, or all enabled system run/tasks and services
+* Show number of total restarts and current respawn count for a
+  service in `initctl status foo`
+* Crashing services no longer have the crash/restart counter reset as
+  soon as they have stabilized.  Instead, a background timer will
+  slowly (every 300 sec) age (decrement) the counter.  This will still
+  catch services that "rage quit", but also those that crash after a
+  longer period of activity
+
+### Fixes
+* Fix #180: user managed (`manual:yes`) services accidentally started
+  by `initctl reload`, regression introduced in Finit v4.0
+* Fix #181: lots of typos all over the tree, by David Yang, Debian
+* Fix #187: fix typos, incl. small cleanup, in doc/bootstrap.md
+* Fix #188: support running on kernels that do not have cgroups v2.
+  When this is detect, all functions related to cgroups support in
+  Finit are disabled, *except* the .conf file parser.  Hence, you
+  may get parse error if you have invalid cgroup configuration in
+  your Finit .conf files
+* Fix #197: `initctl status foo` now shows a focused overview of all
+  matching instances; foo:1, foo:2 -- if only one instance matches the
+  command line argument, or if onle one instance exists, the detailed
+  view is shown, as before
+* Fix #198: a few typos found by Tim Gates
+* Fix #199: avoid using C++ reserved keywords
+* Fix #201: memory leak in usr condition plugin, by Ming Liu, Atlas Copco
+* Fix #203: ensure all filesystems listed in /proc/mounts are properly
+  unumounted on shutdown/reboot, by Robert Andersson, Atlas Copco
+* Fix #210: resizing terminal (smaller) after boot causes empty lines
+  to be inserted between boot progress
+* Fix #211: drop hard-coded 32 character limit in getty, now reads
+  `_SC_LOGIN_NAME_MAX` from `sysconf(3)`
+* Fix #212: service PID file lost after inictl reload, visible from
+  the output from `initctl status foo`
+

+.Sh BOOTING
+.Pp
+Before laucnhing services, the system needs to be bootstrapped.  This
+involves mounting all filesystems (not already mounted by an initramfs)
+in
+.Pa /etc/fstab ,
+ensuring that necessary filesystems like:
+.Pa /dev ,
+.Pa /proc ,
+.Pa /sys ,
+and
+.Pa /run
+are available and can provide the system with the services required.
+.Pp
+With that out of the way, a set of plugins take over:
+.Pp
+.Bl -tag -width bootmisc.so -offset indent
+.It Cm bootmisc.so
+Cleans up stale files from previous boots and default directories are
+created in tmpfs filesystems
+.It Cm modprobe.so
+Probes kernel modules required by the system
+.It Cm procps.so
+Set kernel variables from
+.Pa /etc/sysctl.conf
+et al
+.El
+.Pp
+When the plugins are done, finit reads
+.Pa /etc/finit.conf
+and all other enabled services in
+.Pa /etc/finit.d/* .
+First all services, run/tasks in runlevel S (bootStrap) are started,
+When all run/tasks have completed, Finit changes to the configured
+runlevel (default 2), Processes are started in parallel, in dependency
+order according to their conditions.
+.Pp
+When all services and run/tasks have been started, the console progress
+is disabled and all configured getty services are started.
+.Sh CONDITIONS
+The condition subysystem in Finit was initially created to track PID
+files of daemons.  If service/task B requires service A to have started,
+Finit waits for the PID file of service A to be created/updated before
+it starts service B.  Conversely, if service A is stopped and its PID
+file removed, service B is also stopped.
+.Pp
+The following condition families are available today:
+.Pp
+.Bl -tag -width pid -offset indent
+.It Cm net
+Linux netlink events, e.g. net/route/default, net/eth0/up, and
+net/et0/running
+.It Cm pid

+.It Cm sys
+System conditions, e.g. sys/key/ctrlaltdel and sys/pwr/fail
+.It Cm usr
+User conditions, assert and deassert using
+.Cm initctl cond [set|clr] foo
+.El
+.Sh SIGNALS
+PID 1 is the only process that by default blocks all signals.  Finit

+.Bd -unfilled -offset indent

+.Ed
+.It Cm sysv Oo LVLS Oc Ao COND Ac Ar /path/to/script ARGS Op -- Optional description
+Similar to
+.Cm task
+is the
+.Cm sysv
+stanza, which can be used to call SysV style start/stop scripts.  The
+primary intention for this command is to be able to re-use much of
+existing setup and init scripts in Linux distributions.
+.Pp  
+When entering an allowed runlevel, Finit calls
+.Cm init-script start ,
+when entering a disallowed runlevel, Finit calls
+.Cm init-script stop ,
+and if the Finit .conf, where the
+.Cm sysv
+stanza is declared, is modified, Finit calls
+.Cm init-script restart
+on
+.Cm initctl reload .
+Similar to how
+.Cm service
+stanzas work.
+.Pp
+Forking services started with
+.Cm sysv
+scripts can be monitored by Finit by declaring the PID file to look for:
+.Bd -unfilled -offset indent
+sysv pid:!/path/to/pidfile.pid /path/to/script ...
+.Ed
+.Pp
+The leading '!' is to prevent Finit from managing the PID file, which is
+the default behavior for the
+.Cm pid:
+command modifier.
+.It Cm service Oo LVLS Oc Ao COND Ac Ar /path/to/daemon ARGS Op -- Optional description
+Service, or daemon, to be monitored and automatically restarted if it
+exits prematurely.  Finit tries to restart services that die, by
+default 10 times, before giving up and marking them as
+.Em crashed .
+After which they have to be restarted manually using
+.Cm initctl restart NAME .
+The number of restarts, the delay between each restart, and more is
+configurable, see the options below.
+.Pp  
+For daemons that support it, we recommend appending
+.Cm --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.
+.Pp
+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
+.Cm sysv
+services, using the
+.Cm pid:!/path/to/pidfile.pid
+command modifier syntax.
+.Pp
+.Sy Example: in the case of
+.Cm ospfd
+(below), we omit the
+.Cm -d
+flag (daemonize) to prevent it from forking to the background:
+.Bd -unfilled -offset indent
+service [2345] <pid/zebra> /sbin/ospfd -- OSPF daemon
+.Ed
+.Pp
+.Cm [2345]
+denote the runlevels
+.Cm ospfd
+is allowed to run in, they are optional and default to runlevel 2-5 if
+omitted.
+.Pp
+.Cm <pid/zebra>
+is the condition for starting
+.Cm ospfd .
+In this example Finit waits for another service,
+.Cm zebra ,
+to have created its PID file in
+.Pa /var/run/quagga/zebra.pid
+before starting
+.Cm ospfd .
+Finit watches *all* files in
+.Pa /var/run ,
+for each file named
+.Cm *.pid ,
+.Cm */pid ,
+Finit opens it and find the matching
+.Cm NAME:ID
+using the PID.
+.Pp
+Some services do not maintain a PID file and rather than patching each
+application Finit provides a workaround.  A
+.Cm pid
+modifier 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
+.Pa /var/run
+directory using the
+.Xr basename 3
+of the service.  The full syntax of the
+.Cm pid
+modifier is:
+.Bd -unfilled -offset indent
+pid[:[!][/path/to/]filename[.pid]]
+.Ed
+.Pp
+For example, by adding
+.Cm pid:/run/foo.pid
+to the service
+.Cm /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 the
+.Cm <pid/bar>
+condition.
+.Pp
+If a service should not be automatically started, it can be configured
+as manual with the
+.Cm manual:yes
+command modifier.  The service can then be started at any time by
+running
+.Cm initctl start NAME
+.Pp
+The name of a service, shown by the
+.Cm initctl
+tool, defaults to the basename of the service executable. It can be
+changed with the
+.Cm name:foo
+command modifier.
+.Pp
+As mentioned previously, services are automatically restarted should
+they crash, this is configurable with the following options:
+.Bl -tag -width 1n
+.It Cm restart:NUM
+number of times Finit tries to restart a crashing
+service, default: 10.  When this limit is reached the service is
+marked
+.Em crashed
+and must be restarted manually with
+.Xr initctl 8 .
+.It Cm restart_sec:SEC
+number of seconds before Finit tries to restart
+a crashing service, default: 2 seconds for the first five retries,
+then back-off to 5 seconds.  The maximum of this configured value
+and the above (2 and 5) will be used
+.It Cm norestart
+dont restart on failures, same as
+.Cm restart:0
+.It Cm oncrash:reboot
+when all retries have failed, and the service
+has
+.Em crashed ,
+if this option is set the system is rebooted.  Note, future releases
+may include other
+.Cm oncrash:
+actions.
+.El
+.Pp
+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 command modifier
+.Cm halt:SIGNAL ,
+e.g.,
+.Cm halt:SIGPWR .
+To change the delay between your halt signal and KILL, use the command
+modifier
+.Cm kill:SEC ,
+e.g.,
+.Cm kill:10
+to wait 10 seconds before sending SIGKILL.
+.Pp
+Services support the
+.Cm pre:script
+and
+.Cm post:script
+command actions as well.  These run as the same
+.Cm @USER:GROUP
+as the service itself, with any
+.Cm env:file
+sourced.  The scripts must use an absolute path, but are executed from
+the
+.Cm $HOME
+of the given user.  The scripts are not called with any argument
+(currently), but both get the
+.Cm SERVICE_IDENT=foo
+environment variable set.  Here
+.Cm foo
+denotes the identity of the service, which if there are multiple
+services named
+.Cm foo ,
+may be
+.Cm foo:1 ,
+or any unique identifier specified in the .conf file.  The
+.Cm post:script
+is called with an additional set of environment variables:
+.Bl -tag -offset indent -width 1n
+.It Cm EXIT_CODE=[exited,signal]
+set to one of
+.Cm exited
+or
+.Cm signal
+.It Cm EXIT_STATUS=[num,SIGNAME]
+set to one of exit status code from the program, if it exited normally,
+or the signal name (HUP, TERM, etc.) if it exited due to signal
+.El
+.Pp
+The scripts have a default execution time of 3 seconds before they are
+SIGKILLed, this can be adjusted using the
+.Cm kill:SEC
+modifier syntax.
+.Pp
+.Sy Note:
+the
+.Cm pre:script
+.Em must
+be idempotent, because a service can transition between READY and HALTED
+states any number of times before going to RUNNING.
+.It Cm runparts Aq DIR
+Call
+.Xr run-parts 8
+on
+.Cm 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 bootstrap, runlevel S.
+.Pp
+It can be beneficial to use
+.Cm S01name ,
+.Cm 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.
+.Pp
+Similar to the
+.Pa /etc/rc.local

+terminate or start in the background or you will block Finit.
+.Sy Note:

+applies to all services.
+.Pp
+The size can be given as bytes, without a specifier, or in `k`, `M`,
+or `G`, e.g.
+.Cm size:10M ,
+or
+.Cm size:3G .
+A value of
+.Cm size:0
+disables log rotation.  The default is
+.Cm size:200k .
+.Pp
+The count value is recommended to be between 1-5, with a default 5.
+Setting count to 0 means the logfile will be truncated when the MAX

+The default baud rate is 0, i.e., keep kernel default.
+.Pp
+The `tty` stanza inherits runlevel, condition (and other feature)
+parsing from the `service` stanza.  So TTYs can run in one or many
+runlevels and depend on any condition supported by Finit.  This is
+useful e.g. to depend on `<pid/elogind>` before starting a TTY.

+.Ed
+.It Cm tty Oo LVLS Oc Ao COND Ac Ar CMD DEV Oo noclear Oc Oo nowait Oc
+This form of the
+.Cm tty
+stanza is for using an external getty, like agetty or the BusyBox getty.
+.Pp
+By default, these first two syntax variants
+.Em clear
+the TTY and
+.Em wait
+for the user to press enter before starting getty.
+.Bd -unfilled -offset indent
+tty [12345] /sbin/getty  -L 115200 /dev/ttyAMA0 vt100
+tty [12345] /sbin/agetty -L ttyAMA0 115200 vt100 nowait
+.Ed
+.Pp
+The
+.Cm noclear
+option disables clearing the TTY after each session.  Clearing the TTY
+when a user logs out is usually preferable.
+.Pp  
+The
+.Cm nowait
+option disables the
+.Cm Please press Enter to activate console
+message before actually starting the getty program.  On small and
+embedded systems running multiple unused getty wastes both memory and
+CPU cycles, so `wait` is the preferred default.
+.Pp
+The
+.Cm nologin
+option disables getty and
+.Pa /bin/login ,
+and gives the user a root (login) shell on the given TTY
+.Cm DEV
+immediately.  Needless to say, this is a rather insecure option, but can
+be very useful for developer builds, during board bringup, or similar.
+.Pp
+Notice the ordering, the
+.Cm TERM
+option to the built-in getty must be the last argument.
+.Pp
+Embedded systems may want to enable automatic `DEV` by supplying the
+special
+.Cm @console
+device.  This works regardless weather the system uses
+.Cm ttyS0 , ttyAMA0 ,  ttyMXC0 ,
+or anything else.  Finit figures it out by querying sysfs:
+.Pa /sys/class/tty/console/active .
+The speed can be omitted to keep the kernel default.
+.Pp
+Most systems get by fine by just using `console`, which will evaluate
+to
+.Pa /dev/console .
+If you have to use
+.Cm @console
+to get any output, you may have some issue with your kernel config.
+.Bd -unfilled -offset indent
+tty [12345] @console noclear vt220
+.Ed
+.Pp
+On really bare bones systems, or for board bringup, Finit can give you a
+shell prompt as soon as bootstrap is done, without opening any device
+node:
+.Bd -unfilled -offset indent
+tty [12345789] notty
+.Ed
+.Pp
+This should of course not be enabled on production systems.  Because it
+may give a user root access without having to log in.  However, for
+board bringup and system debugging it can come in handy.
+.Pp
+One can also use the
+.Cm service
+stanza to start a stand-alone shell:
+.Bd -unfilled -offset indent
+service [12345] /bin/sh -l
+.Ed
+.Pp
+.It Cm tty Oo LVLS Oc Ao COND Ac Oo notty Oc Oo rescue Oc
+The third
+.Cm tty
+form is for board bringup and the
+.Cm rescue
+boot mode.  No device node is required in this variant, the same output
+that the kernel uses is reused for stdio.  If the
+.Cm rescue
+option is omitted, a shell is started.  The flags
+.Cm nologin , noclear ,
+and
+.Cm nowait
+are implied.   If the
+.Cm rescue
+option is set the bundled
+.Pa /libexec/finit/sulogin
+is started to present a bare-bones root login prompt.  If the root
+(uid:0, gid:0) user does not have a password set, no rescue is possible.
+.El
+.Sh COMMAND MODIFIERS
+The run/task/tty/service/sysv stanzas take modifiers, or options, to
+control their behavior.  This section lists them with their limitations.
+All modifiers must be placed between the stanza and its command.
+.Bl -tag -width 1n
+.It Cm @user:group
+Every
+.Cm run , task ,
+or
+.Cm service
+can also list the privileges the
+.Cm /path/to/cmd
+should be executed with.  Prefix the command with
+.Cm @USR[:GRP] ,
+group is optional, like this:
+.Bd -unfilled -offset indent
+run [2345] @joe:users logger "Hello world"
+.Ed
+.Pp
+For multiple instances of the same command, e.g. a DHCP client or
+multiple web servers, add
+.Cm :ID
+somewhere between the
+.Cm run , task , service
+keyword and the command, like this:
+.Bd -unfilled -offset indent
+service :80  [2345] httpd -f -h /http -p 80   -- Web server
+service :8080[2345] httpd -f -h /http -p 8080 -- Old web server
+.Ed
+.Pp
+Without the
+.Cm :ID
+to the service the latter will overwrite the former and only the old web
+server would be started and supervised.
+.It Cm log:/path/to/file
+Redirect stdout/stderr of a command to the given log file.  See the
+global log directive, above, for details on log rotation.
+.It Cm log:console
+Redirect stdout/stderr of a command to
+.Pa /dev/console ,
+only use this for debugging or bringup.
+.It Cm log:null
+Redirect stdout/stderr of a command to
+.Pa /dev/null .
+.It Cm log:prio:facility.level,tag:ident
+Redirect stdout/stderr of a command to syslog using the given priority
+and tag identity.
+.Bd -unfilled -offset indent
+service log:prio:user.warn,tag:ntpd /sbin/ntpd pool.ntp.org -- NTP daemon
+.Ed
+.It Cm log
+Default
+.Cm prio
+is
+.Cm daemon.info
+and the default
+.Cm tag
+identity is the basename of the service or run/task command.
+.El
+.Sh RESCUE MODE
+Finit supports a rescue mode which is activated by the
+.Cm rescue
+option on the kernel command line.  The rescue mode comes in two
+flavors:
+.Em traditional
+and
+.Em fallback .
+.Ss Traditional
+This is what most users expect.  A very early maintenance login prompt,
+served by the bundled
+.Pa /libexec/finit/sulogin
+program, or the standard
+.Cm sulogin
+from util-linux or BusyBox is searched for in the UNIX default
+.Cm $PATH .
+If a successful login is made, or the user exits (Ctrl-D), the rescue
+mode is ended and the system boots up normally.
+.Pp
+.Sy Note:
+if the user (UID 0 and GID 0) does not have a password, or
+.Em the account is locked ,
+the user is presented with a password-less prompt:
+.Cm "Press enter to enter maintenance mode." ,
+which opens up a root shell.
+.Ss Fallback
+If no
+.Cm sulogin
+program is found, Finit tries to bring up as much of its own
+functionality as possible, yet limiting many aspects, meaning; no
+network, no`fsck` of file systems in
+.Pa /etc/fstab ,
+no
+.Pa /etc/rc.local ,
+no
+.Cm runparts ,
+and most plugins are skipped (except those that provide functionality
+for the condition subsystem).
+.Pp
+Instead of reading
+.Pa /etc/finit.conf
+et al, system configuration is read from
+.Pa /lib/finit/rescue.conf ,
+which can be freely modified by the system administrator.
+.Pp
+The bundled default `rescue.conf` contains nothing more than:
+.Bd -unfilled -offset indent
+runlevel 1
+tty [12345] rescue
+.Ed
+.Pp
+The
+.Cm tty
+has the
+.Cm rescue
+option set, which works similar to the board bring-up tty option
+.Cm notty .
+The major difference being that `sulogin` is started to query for
+root/admin password.  If
+.Cm sulogin
+is not found,
+.Cm rescue
+behaves like
+.Cm notty
+and gives a plain root shell prompt.
+.Pp
+If Finit cannot find
+.Pa /lib/finit/rescue.conf
+it defaults to:
+.Bd -unfilled -offset indent
+tty [12345] rescue
+.Ed
+.Pp
+There is no way to exit the
+.Em fallback
+rescue mode.
+.Sh SERVICE ENVIRONMENT
+Finit supports sourcing environment variables from
+.Pa /etc/default/* ,
+or similar.  This is a common pattern from SysV init scripts, where the
+start/stop script is a generic script for the given service,
+.Cm foo ,
+and the options for the service are sourced from the file
+.Pa /etc/default/foo .
+Like this:
+.Bd -unfilled -offset indent
+/etc/default/foo:
+
+    FOO_OPTIONS=--extra-arg="bar" -s -x
+
+/etc/finit.conf:
+
+    service [2345] env:-/etc/default/foo foo -n $FOO_OPTIONS -- Example foo daemon
+.Ed
+.Pp
+Here the service
+.Cm foo
+is started with
+.Op Fl -n ,
+to make sure it runs in the foreground, and the with the options found
+in the environment file.  With the
+.Cm ps
+command we can see that the process is started with:
+.Bd -unfilled -offset indent
+foo -n --extra-arg=bar -s -x
+.Ed
+.Pp
+.Sy Note:
+the leading `-` determines if Finit should treat a missing environment
+file as blocking the start of the service or not.  When `-` is used, a
+missing environment file does
+.Em not
+block the start.
+.Sh SERVICE WRAPPER SCRIPTS
+If your service requires to run additional commands, executed before the
+service is actually started, like the systemd `ExecStartPre`, you can
+use a wrapper shell script to start your service.
+.Pp
+The Finit service
+.Cm .conf
+file can be put into
+.Pa /etc/finit.d/available ,
+so you can control the service using
+.Cm initctl .
+Then use the path to the wrapper script in the Finit
+.Cm .conf
+service stanza.  The following example employs a wrapper script in
+.Pa /etc/start.d .
+.Bd -unfilled
+/etc/finit.d/available/program.conf:
+
+    service [235] <!> /etc/start.d/program -- Example Program
+
+/etc/start.d/program:
+
+    #!/bin/sh
+    # Prepare the command line options
+    OPTIONS="-u $(cat /etc/username)"
+
+    # Execute the program
+    exec /usr/bin/program $OPTIONS
+.Ed
+.Pp
+.Sy Note:
+the example sets
+.Cm <!>
+to denote that it doesn't support SIGHUP.  That way Finit will
+stop/start the service instead of sending SIGHUP at restart/reload
+events.
+.Sh CGROUPS
+There are three major cgroup configuration directives:
+.Pp
+.Bl -enum -offset indent -compact
+.It
+Global top-level group: init, system, user, or a custom group
+.It
+Selecting a top-level group for a set of run/task/services
+.It
+Per run/task/service limits
+.El
+.Pp
+Top-level group configuration.
+.Bd -unfilled -offset indent
+# Top-level cgroups and their default settings.  All groups mandatory
+# but more can be added, max 8 groups in total currently.  The cgroup
+# 'root' is also available, reserved for RT processes.  Settings are
+# as-is, only one shorthand 'mem.' exists, other than that it's the
+# cgroup v2 controller default names.
+cgroup init   cpu.weight:100
+cgroup user   cpu.weight:100
+cgroup system cpu.weight:9800
+.Ed
+.Pp
+Adding an extra cgroup
+.Cm maint/
+will require you to adjust the weight of the above three.  We leave
+.Cm init/
+and
+.Cm user/
+as-is reducing weight of
+.Cm system/
+to 9700.
+.Bd -unfilled -offset indent
+cgroup system cpu.weight:9700
+
+# Example extra cgroup 'maint'
+cgroup maint  cpu.weight:100
+.Ed
+.Pp
+By default, the
+.Cm system/
+cgroup is selected for almost everything.  The
+.Cm init/
+cgroup is reserved for PID 1 itself and its closest relatives.  The
+.Cm user/
+cgroup is for local TTY logins spawned by getty.
+.Pp
+To select a different top-level cgroup, e.g.
+.Cm maint/ ,
+one can either define it for a group of run/task/service directives in a
+.Cm .conf
+or per each stanza:
+.Bd -unfilled -offset indent
+cgroup.maint
+service [...] <...> /path/to/foo args -- description
+service [...] <...> /path/to/bar args -- description
+.Ed
+.Pp
+or
+.Bd -unfilled -offset indent
+service [...] <...> cgroup.maint /path/to/foo args -- description
+.Ed
+.Pp
+The latter form also allows per-stanza limits on the form:
+.Bd -unfilled -offset indent
+service [...] <...> cgroup.maint:cpu.max:10000,mem.max:655360 /path/to/foo args -- description
+.Ed
+.Pp
+Notice the comma separation and the
+.Cm mem.
+exception to the rule: every cgroup setting maps directly to cgroup v2
+syntax.  I.e.,
+.Cm cpu.max
+maps to the file
+.Pm /sys/fs/cgroup/maint/foo/cpu.max .
+There is no filtering, except for expanding the shorthand
+.Cm mem.
+to
+.Cm memory. ,
+if the file is not available, either the cgroup controller is not
+available in your Linux kernel, or the name is misspelled.
+.Pp
+Linux cgroups and details surrounding values are not explained in the
+Finit documentation.  The Linux admin-guide cover this well:
+.Lk https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html
+.Sh LIMITATIONS
+As of Finit v4 there are no limitations to where
+.Cm .conf
+settings can be placed.  Except for the system/global
+.Cm rlimit
+and
+.Cm cgroup
+top-level group declarations, which can only be set from
+.Pa /etc/finit.conf ,
+since it is the first
+.Cm .conf
+file Finit reads.
+.Pp
+Originally,
+.Pp /etc/finit.conf
+was the only way to set up a Finit system.  Today it is mainly used for
+bootstrap settings like system hostname, early module loading for
+watchdogd, network bringup and system shutdown.  These can now also be
+set in any
+.Cm .conf
+file in
+.Pa /etc/finit.d .
+.Pp
+There is, however, nothing preventing you from having all configuration
+settings in
+.Pa /etc/finit.conf .
