[systemd-devel] [PATCH] service: kill processes with SIGKILL on

Thx for the fast response and alternative patch. I tested it in my 
environment as well and it works as expected killing the processes 
without executing the stop stuff.

This might depend a bit on how one sees the intention of the stop stuff. 
You regard ExecStop and ExecStopPost as mechanism to support stopping a 
service using any thinkable way.

If you use ExecStopPost to do things (cleanin up or whatever) whenever 
the process has been stopped, this functionality might even make sense 
when the process is killed due to a missed watchdog notigication.

Btw: ExecStopPost and ExecStop are called, when a process is killed by 
an external kill or even when it exits itsself properly. So this is 
somehow similar to the watchdog case, isn't it?
