Right, this is then the normal exit (error) status code + "0" if the
program could successfully be restarted.

Hmm, good question. RedHat's 'condrestart' usually does:
[some running test ] && restart || :
and SuSE's try-restart currently (taken from /etc/init.d/skeleton):
$0 status >/dev/null && $0 restart
- If running the restart exit status code is given
- If not running, SuSE returns a 1 while RedHat returns a 0
Returning a success (= 0) is in so far the right thing since that is
exactly want is requested: don't restart if not running.
On the other hand: It is nice to know whether something has
happend or not and therefore returning a "7" makes sense too.
I do not want to decide this. At least not without further comments.
