Add explicit argument separator before username to ensure correct
parsing of the login command regardless of username format.  This
follows best practices for command execution and prevents unexpected

Joachim Wiberg b695b46a9d Revert last part of 91a9c83, fallback SIGKILL when stopping services
When a service is stopped, but does not respond to the default SIGTERM,
a fallback kicks in after 3 seconds (default) to send SIGKILL.  Since
91a9c83 (v3.2-rc2) this has however not worked since the signal was
only sent to the process group.

It is the job of service_monitor(), when it reaps the process leader,
to forward the signal to the process group.

Joachim Wiberg 3add682be3 Wait for post:script and cleanup:script before returning OK
This change introduces two new states for the big Finit state machine:
runlevel-clean and reload-clean.  Here Finit now waits for any post or
cleanup script to finish before returning OK to the initctl command.

Additionally, the service state machine has been updated to ensure a
run/task/sysv/service calls any post or cleanup script before they are
removed.  A new 'dead' state for svc_t is introduced which any removed
svc_t ends up in now instead of becing collected from 'halted' state.

az 3cfe0a33b8 fstab with UUID/LABEL: nofail handling for fsck
add support for 'nofail' fstab option. if present, finit's fsck invocation ignores errors for this device.

this is useful if you have an fstab entry for a device with UUID= or LABEL= which isn't always present and which you'd like to not
bail on (so you set nofail). in this case finit leaves the presence-or-not decision to fsck, which exits nonzero.

for block devices that are directly listed in fstab this change isn't important, because for such finit looks for the blockdev's existence and skips the fsck if n/a.

Consider the case where container@.conf is an available template.  When

because foo is instantiated.

Up until this change, all template siblings were considered "dirty" if a
new one was created or updated.  Skipping realpath() for all files that
have a '@' works around the problem.

Joachim Wiberg 6be16f2f6d Fix buggy --with-rtc-date=DATE, introduced in Finit v4.4
In 42ef3d3c, for v4.4-rc1, support for setting a custom RTC restore date
was introduced.  Unfortunately the configure script was wrong and caused
config.h to contain

    #define RTC_TIMESTAMP_CUSTOM "$rtc_date"

instead of

    #define RTC_TIMESTAMP_CUSTOM "2023-04-10 14:35:42"

Furthermore, the error handling for strptime() was wrong, so the restore
date was always reverted to the default.

This patch fixes both issues and extends the DATE of --with-rtc-date to
also include seconds.

Joachim Wiberg bc8118d515 Fix #418: support systems with a broken RTC
This patch introduces a new configure option --with-rtc-file=FILE.  When
enabled the RTC plugin detects missing RTC device and falls back to save
and restore system time from a file instead.  When --with-rtc-file is
used without an argument the default file is /var/lib/misc/rtc, but the
feature itself is disabled by default.

The usefulness of this feature may not be obvious at first, but some
systems are equipped with an RTC that resets to a random date at power
on.  This can be really bad in the case the date is far in the future,
because an NTP sync would then cause time skips backwards, which shows
up in logs and causes a whole lot of pain in alarm systems.

The solution is to disable the RTC driver or device tree node, and when
Finit starts up, the RTC plugin detects a the device node and instead
restores time from the last save game.  Meaning time will always only
move forwards.

NOTE: when Finit is built --with-rtc-file we always save to disk, but
      only restore from the "save game" if restoring from RTC fails.
      If the system has no RTC we always restore from disk.

      As an added bonus, this change also makes sure to periodically
      sync also the RTC with the system clock.  Useful for systems
      that do not run an NTP client.

Joachim Wiberg 46ffa81f5c Only mark rdeps dirty if main service is nohup
This patch changes a behavior that's been default since Finit 4.0,
introduced in 4d05bf9 with 4.0-rc2.

If service B depends on A and A needs to be reloaded, then B may be
affected.  If A is declared as NOHUP <!>, then A will be stopped and
restarted, during which time the condition it provides is removed,
and B will also be stopped.

However, and as of this patch, if A is declared supporting HUP, then the
condition A provides will only go into flux, during which time B will be
SIGSTOPed instead of needing to be reloaded.

Ming Liu 3e3e9aadf5 tmpfiles.c: prevent nftw follow symbolic links
When dealing with "L+" and "R", the function call 'nftw' should not
follow symbolic links, otherwise, it would also delete the targets
which is wrong.

For instance, if there is already a symbolic link:
```
/path/to/the/link -> /path/to/some/folder
```

if we set the following in a tmpfile conf:

```
L+ /path/to/the/link -    -    -     - /path/to/the/target
```

the result would be /path/to/some/folder also get deleted, which it
should not.

it could be even worse, when the symbolic link already is pointing to:
/path/to/the/target, the whole /path/to/the/target would be deleted on
next system boot.

Mathias Thore a0685219cf Avoid remounting already mounted /run and /tmp directories
Adds the function fistmpfs to determine if a new tmpfs mount should be
performed on /run and /tmp. The function supports cases where more
complex mount hierarchies are in use, including overlayfs backed mounts.

Joachim Wiberg 340cae4afd Change default behavior, allow kernel logs to console
A Linux system booted with the kernel command line option 'quiet' only
logs error (and above) severity messages to the console.  For embedded
systems, which is the primary target for Finit, this is what you want
to see.

Hence, and after careful consideration, this patch changes the default
behavior of Finit to allow kernel logs to the console.  A build-time
configure flags, --disable-kernel-logging, has been added to restore
legacy behavior.

All relevant changes are documented in this file.
[4.11][] - 2025-03-27
---------------------
### Changes
- Update documentation regarding transition from runlevel S to 2, how
run/tasks must "complete" before Finit can move to the next runlevel
- Improve argument handling in bundled getty when launching login
### Fixes
- Fix #432: allow services in `setup` state to be stopped. This fixes
a serious blocker introduced in 4.10 that prevented systems from
being rebooted when any service was in this state
- Fix fallback `SIGKILL` when stopping a service with `SIGTERM` does
not work. This fixes a serious issue with services not responding to
the default `SIGTERM`
- Fix pre/post/ready/cleanup script execution if service has an
optional `env:file` (leading `-`)
[4.10][] - 2025-03-03
---------------------
### Changes
- Add support for `cleanup:[0-3600,]script`, runs before service is
removed, unlike `post:script` that runs when service is stopped
- Improved entropy gathering in tertiary fallback of urandom plugin
- Reclassify `sysv` from run/task class to `service`
### Fixes
- Fix #427: using an external getty with custom login program cause
Finit to use login program as the getty command
- Fix #428: allow `sysctl` path to be set at build time
- Fix #429: regression in v4.9 causing Finit to segfault at shutdown
- Fix possible memory leak when sourcing a service `env:file`
- Finit now waits until all `post:scripts` have run before returning
OK to `initctl <reload|runlevel>`. This also applies to the new
`cleanup:scripts` introduced in this release
- RFC3154 conformance formatting fix for `/dev/kmsg` fallback logging
[4.9][] - 2025-02-15
--------------------
> [!CAUTION]
> This release changes how Finit reacts to the exit status of `pre:`
> scripts. Finit will now no longer start the main process if its
> `pre:` script fails for any reason. So, if you have pre scripts that,
> e.g., create directories, make sure they are idempotent.
### Changes
- Add individual timeout (optional) support for pre/post/ready scripts
- Add support for systems with broken RTC, i.e., those that at power-on
may reset the RTC to a random date instead of zero, issue #418
- Add support for detecting "in-container" when in `systemd-nspawn`
- Check exit status of `pre:` scripts, on failure drive service/sysv to
`crashed` state. (The exit code of `post:` scripts remain ignored)
- All pre/post/ready scripts are now also searched for in `$PATH`
- Reset color attributes and clear screen when starting up. This is
for boot loaders like GRUB, which leave background color artifacts
### Fixes
- Fix #415: only mark reverse-dependencies "dirty" if the main service
does not support SIGHUP. This helps avoid unnecessary restarts of
services that depend on a service that supports SIGHUP
- Fix #417: leaking inotify watchers in the cgroup subsystem
- Fix #421: add support for `nofail` mount option in `/etc/fstab`
- Fix #425: ordering bug in detecting .conf file changes to services
and `initctl reload`, or runlevel changes
- Fix `initctl touch` of template services, previously marking a
service created from a template as "dirty" did not take
- Fix unintended restart of template "siblings". I.e., `initctl touch`
of instantiated template service A affected B from same template
- Fix buggy `--with-rtc-date=DATE` configure option
- Fix kill on timeout of pre/post/ready scripts
[4.8][] - 2024-10-13
--------------------
### Changes
- Avoid remounting already mounted `/run` and `/tmp` directories. This
extends the existing support for detecting mounted directories to
include complex mount hierarchies are in use, overlayfs and tmpfs
mounts. Feature by Mathias Thore, Atlas Copco
- getty: trigger /etc/issue compat mode for Alpine Linux
- tmpfiles.d: skip `x11.conf` unless X11 common plugin is enabled
- tmpfiles.d: ignore x/X command, nos support for cleanup at runtime
- Drop debug mode `-D` from `udevd` in `hotplug.conf.in`, allow the
user to set this in `/etc/default/udevd` instead
- Certain initctl APIs at bootstrap are not supported, update warning
log to include command (number) for troubleshooting, issue #398
- Add support for hwrng to urandom plugin and check for empty seed
- Add `runparts -b` (batch mode) support, disables escape sequences
- New configure `--without-rc-local`, disables `/etc/rc.local` support
- New configure `--disable-cgroup` option, disables cgroup v2 detection
- `initctl show template@foo.conf` now shows how an enabled template
service has been evaluated by Finit, issue #411
- Extend `initctl` timeout connecting and waiting for Finit reply. The
previous 2 + 2 second poll timeout has proved to be too short on more
complex systems. Now a 15 + 15 second timeout is applied which should
be more resistant to temporary overload scenarios, issue #407
### Fixes
- Fix #397: system shutdown/reboot can block on console input if action
is started remotely (ssh). Caused by legacy TTY screen size probing,
removed from both bootstrap and shutdown/reboot
- Fix #400: both `HOOK_MOUNT_ERROR` and `sulogin()` fail to trigger on
either mount or `fsck` errors. Problem caused by unresolved status
from pipe, calling `pclose()` without extracting exit status
- Fix #402: `initctl touch` does not respect `-n` (no error) flag
- Fix #403: `initctl touch` does not support template services
- Fix #404: possible undefined behavior when `--with-fstab=no` is set
- Fix #405: `@console` getty does not work with `tty0 ttyS0`
- Fix #409: prevent tmpfiles from following symlinks for `L+` and `R`,
otherwise symlink targets would also be removed. Found and fixed by
Mathias Thore and Ming Liu, Atlas Copco
- Fix #414: Frr Zebra immediately restarts on `initctl stop zebra`.
The fix likely works for all Frr/Quagga services due to the way they
create and delete their pid file
- Cosmetic issue with `[ OK ]` messages being printed out of order at
shutdown/reboot. Caused by nested calls to `service_stop()`
- Cosmetic issue with duplicate "Restoring RTC" message at bootstrap

task [S] /lib/console-setup/console-setup.sh
service [S12345] env:-/etc/default/rsyslog rsyslogd -n $RSYSLOGD_ARGS
After runlevel S, Finit proceeds to runlevel 2. This can be changed in
`/etc/finit.conf` using the `runlevel N` directive, or by a script
running in runlevel S that calls, e.g., `initctl runlevel 9`. The
latter is useful if startup scripts detect problems outside of Finit's
control, e.g., critical services/devices missing or hardware problems.
When bootstrap has completed, Finit moves to runlevel 2. This can be
changed in `/etc/finit.conf` using the `runlevel N` directive, or by a
script running in runlevel S that calls, e.g., `initctl runlevel 9`.
The latter is useful if startup scripts detect problems outside of
Finit's control, e.g., critical services/devices missing or hardware
problems.
Before starting the services in runlevel 2, Finit first stops everything
that is not allowed to run in 2, and then brings up networking.
Networking is expected to be available in all runlevels except: S, 1
(single user level), 6, and 0. Networking is enabled either by the
`network script` directive, or if you have an `/etc/network/interfaces`
file, Finit calls `ifup -a` -- at the very least the loopback interface
is brought up.
Each runlevel must be allowed to "complete". Meaning, all services in
runlevel S must have started and all run/tasks have been started and
collected (exited). Finit waits 120 seconds for all run/tasks in S to
complete before proceeding to 2.

When stopping a service (run/task/sysv/service), either manually or

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.,

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. However, if the process has not
been collected within 3 seconds, Finit will send `SIGKILL`. To stop the
process using a different signal than `SIGTERM`, use `halt:SIGNAL`,
e.g., `halt:SIGPWR`. To change the delay between the stop signal and
KILL, use the option `kill:<1-60>`, e.g., `kill:10` to wait 10 seconds

Services support `pre:script` and `post:script` actions as well. These
run as the same `@USER:GROUP` as the service itself, with any `env:file`
sourced. The scripts must use an absolute path, but are executed from
the `$HOME` of the given user. The scripts are not called with any
argument (currently), but both get the `SERVICE_IDENT=foo` environment
variable set. Here `foo` denotes the identity of the service, which if
there are multiple services named `foo`, may be `foo:1`, or any unique
identifier specified in the .conf file. The `post:script` is called
with an additional set of environment variables:
Services, including the `sysv` variant, support pre/post/ready and
cleanup scripts:
- `EXIT_CODE=[exited,signal]`: set to one of `exited` or `signal`

* `post:[0-3600,]script` -- called after the sysv/service has stopped
* `ready:[0-3600,]script` -- called when the sysv/service is ready
* `cleanup:[0-3600,]script` -- called when run/task/sysv/service is removed
The optional number (0-3600) is the timeout before Finit kills the
script, it defaults to the kill delay value and can be disabled by
setting it to zero. These scripts run as the same `@USER:GROUP` as the
service itself, with any `env:file` sourced. The scripts are executed
from the `$HOME` of the given user. The scripts are not called with any
argument, but get a set of environment variables:
* `SERVICE_IDENT=foo:1`
* `SERVICE_NAME=foo`
* `SERVICE_ID=1`
The `post:script` is called with an additional set of environment
variables. Yes, the text is correct, the naming was an accident:
- `EXIT_CODE=[exited,signal,crashed]`: normal exit, signaled, or
crashed
- `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
These script actions *must terminate*, so they have a default execution
time of 3 seconds before they are SIGKILLed, this can be adjusted using
the above `kill:SEC` syntax.
When a run/task/sys/service is removed (disable + reload) it is first
stopped and then removed from the runlevel. The `post:script` always
runs when the process has stopped, and the `cleanup:script` runs when
