when the main prcoess crashes surely, that's what it's all about but
none of the actions are appealing for most services :-)

FailureAction=, SuccessAction=
Configure the action to take when the unit stops and enters a failed
state or inactive state. Takes one of none, reboot, reboot-force,
reboot-immediate, poweroff, poweroff-force, poweroff-immediate, exit,
and exit-force. In system mode, all options are allowed. In user mode,
only none, exit, and exit-force are allowed. Both options default to none.

If none is set, no action will be triggered. reboot causes a reboot
following the normal shutdown procedure (i.e. equivalent to systemctl
reboot). reboot-force causes a forced reboot which will terminate all
processes forcibly but should cause no dirty file systems on reboot
(i.e. equivalent to systemctl reboot -f) and reboot-immediate causes
immediate execution of the reboot(2) system call, which might result in
data loss (i.e. equivalent to systemctl reboot -ff). Similarly,
poweroff, poweroff-force, poweroff-immediate have the effect of powering
down the system with similar semantics. exit causes the manager to exit
following the normal shutdown procedure, and exit-force causes it
terminate without shutting down services. When exit or exit-force is
used by default the exit status of the main process of the unit (if this
applies) is returned from the service manager. However, this may be
overridden with FailureActionExitStatus=/SuccessActionExitStatus=, see
below.
