Fedora startup script help

[Muhammad Imran]

Sorry, forgot to mention that I can put a '&' after "daemon $SERVER" 
command, that would make it run in the background, but daemon is more than 
simply a process running in back-ground. I want to run it as daemon as 
opposed to a user process running in background.

thanks
