I've tried the service command, and it makes no difference.

I'm using Linux (Fedora 7). It already has a Mailman init script. It has a line:
   daemon $PYTHON $MAILMANCTL -s -q start

daemon is a function in /etc/rc.d/functions which does this:
   $nice runuser -s /bin/bash - $user -c "$corelimit >/dev/null 2>&1 ; $*"

Is it possible for mailmanctl to disassociate itself from the terminal?
Would the setsid() system call help?
