Not tested by me, and also not many real comments.

I'd create a PID file too, cfr. S01logging. But it's not required.

Same here.

Unfortunately, if the user has a different start script, chances are
that it will also have a different number. Not sure how to fix that,
though, unless we re-implement something like Debian's update-rc.d.
Also, two things here would be nice to generalize:
- Checking a sub-.config option, which is useful in a large number of cases.
- Installing an init script.
But those are not for this patch.

Uninstall of S41inetd and inetd.conf is missing.
