Old-fashioned and deprecated, you Slackware fan you! :-)

A good thing when init-scripts behave like that is to check output and logs.

Secondly, I don't know about RH, but all other dists I've used have a 
skeleton init-script to be copied and modified for creating new 
init-scripts.
It should take arguments "start", "stop" an "restart" as a minimum. You 
should exit with correct codes to tell the daemon script if start really was 
OK or not.
That's the way to do it.

For using the script at http://www.bluecows.com/scripts/jabberd.start make 
sure your Jabber server actualy is in "/opt". According to Linux standards 
anything not distribution related should end up in "/usr/local", I think 
"/opt" is an invention of Sun?

Hehe, standards are nice only if used. ;-)

I'm including a small init-script. It does not use the nice color stuff that 
RH and other RH-based dists use, but it works fine on my Debian and 
Slackware.
