Hi Bernd!

If you ever tried to run an RA by hand, you wouldn't have asked, I guess.
The RA needs ist parameters from environment, while typical LSB scripts take their configuration from files (/etc/sysconfig). I hope you are not talking about using LSB scripts as RAs.

I hope you are not expecting init (etc/init.d) to do periodic status checks (actually init can check the status of processes it stared directly, but I'm sure you know that).
