But you only have to do it right once (in a procedure/function):
If the PID file exists
then
if the PID file is newer than the time of reboot
then
if there is a process with this pid
if the process having that pid matches a given pattern
then
the process is alive
else
another process has this PID; remove stale PID file
fi
else
remove stale pid file
fi
else
remove stale pid file
fi
fi
Everything else ist just wrong IMHO.
