Since a forking service, e.g. a sysv init script, will exit very early
we cannot log the same as for regular services "Starting foo[123]", so
instead we log "Started bar[321]" when we get the pidfile update and
the same when stopping a forking service, log "Stopped bar[321]" when
we collect the PID.

This change adds the following service conditions, which can be used to
synchronize other stanzas:
- service/foo/running
- service/foo/halted
- service/foo/missing
- service/foo/crashed
- service/foo/stopped
- service/foo/busy
- service/foo/restart

This reverts commit c63279630b which
clearly was not needed to fix the problem. After this revert the
test(s) still pass, but now we can also start bridge-stp, e.g.
bridge-stp br0 start

A forking service, e.g. a SysV init script, that returns is no longer
running, even though the monitored service may still be starting. We
must mark the svc->pid as terminated until we know more -- otherwise
we may stall on a shutdown at that exact point.
Also, when shutting down, and stopping all services, ensure we do not
start the carousel for non-existing PIDs. This might also cause our
stalling at shutdown.

- Add `type:forking` service option to trigger guessing pidfile to
watch for, instead of `pid:!foo` option, which is not intuitive.
This option may likely also survive into the new file format :)
- Update docs and add examples
- Update start-stop-serv.sh test case with this new variant

Before this fix, a service declared with respawn could not be changed at

No point waiting for SysV start/stop scripts to finish, PID 1 should not
risk getting blocked forever by broken scripts. Instead we fork them off
and forget about them until they terminate. If they are buggy and don't
finish, it's the problem of the admin.

We want to find the PID of the daemon the init script starts, so we need

SysV init scripts should not go to "done" state but "halted" so we can
do: `initctl stop foo; initctl start foo`, like we do for our regular
monitored services.

Turns out the kill(2) syscall returns ENOENT, not ESRCH, in our test
suite. Don't know why, the man page never mentions ENOENT, only the
ESRCH code. Let's check for both, either way ithe PID is not there.

A service may have unexpectedly died, and we never got the signal, so
when stopping services we must set the new state after we've tried to
stop the service. Otherwise the svc_set_state() function starts a
background timer for the SIGKILL job, which may block a reboot.
The kill() syscall tells us if the service was there or not, if not we
must clean up and go to HALTED state.

In commit f0f358a13:
[ service.c: set/clear condition 'done' for run tasks ]
a runtask done condition would be set/cleared when entering DONE/HALTED
states, but it did not cover all the user cases, for instance, sometimes
an end user may want to know if a runtask has finished sucessfully or
to decide what to do on its failures.
So we now change the conditions to: tsktype/tskname/success and
tsktype/tskname/failure.
And this change not only applies to run/task types, but also applies to
sysv type, in case it fails, a sysv/tskname/failure condition would be
set.

A regression was introduced by commit f0f358a1:
[ service.c: set/clear condition 'done' for run tasks ]
svc->type is a integer but mistakenly being used as string, which will
cause crash.

We like to know when a runtask (run/task/sysv)is done, so as to start
the services that depending on it, set a oneshot condition 'done' for
that case and clear it when runtask services enter HALTED state.

Traditionally we've reset the service restart counter on two occasions:
1) when a service reaches its max crash count (default 10), and
2) when a service somehow "stabilizes"
In the second case the service is restored to normal running state and
we "forget" its bad previous behavior. Meaning we cannot catch daemons
that act in an unstable manner outside the "rage quit" scenario.
This patch allows for slowing aging (decrementing) the restart counter
once every five minutes. Meaning we still catch rage quitters but now
are also able catch other types of misbehavior.

A timeout is not the same as a restart delay, which this option really
controls, but the name restart_delay is a bit too long. Hence, this
obvious name so there's no ambiguity what unit we're dealing with.
Keeping restarttmo:SEC as a compatibility setting for the benefit of
the original authors, for now.

Due to an unfortunate name clash with the DirectFB project LiTE, the
libite (-lite) project had to change its header namespace from
lite/*.h -> libite/*.h
This patch adds support for the new namepace in Finit, triggered by the
define _LIBITE_LITE, from the .pc file read by pkg-config. This should
only be needed on systems that install libite without the compatibility
symlink lite -> libite/ in the staging include directory.

It would be good if we can control the services more specifically with
the following parameters like:
restart:N - how many times shall the service to be restarted on
failures (<10), the default max is 10.
restart_tmo - the timeout of the restarting.
norestart - dont restart on failures.
oncrash - once all retrying also fail, how to deal with it,
rebooting or ignoring the failures.

Once upon a time, SIGSTOP was used to pause Finit during flashing (MTD)
of a system image. This to prevent Finit from accidentally starting any
programs, i.e., reading from flash disk during or after upgrade.
This was quite intrusive, and has possible nasty side effects, e.g., any
process with root access sends SIGSTOP prevents TTY login. So this patch
now removes the functionality and recommends using a dedcicated runlevel
for such critical tasks instead.

This patch adds a `respawn` flag for services and ttys, always set for
ttys, that allows bypassing the crash/restart counter and immediately
restart a 'crashing' service.
For tty type services this is the expected behavior, but for regular
services it is not. That is why `respawn` flags is not advertised in
the docs.
