[Citadel Development] Re: Removed background and restart from citserver.

The rc system fully detaches it from the entire call stack, in the end it just looks like init ran the daemon.  The rc system is really just a series of shell scripts, nothing too fancy.  That's why PID files are so important, the rc system uses those to figure out which PID to send signals to.

I have to go examine other BSD rc scripts, but I'm guessing they simply do "&" to put a process in the background, and then they keep track of the pid so they can SIGTERM it later.
