Debian uses following snippet to stop the daemons:

do_stop()
{
        # Return
        #   0 if daemon has been stopped
        #   1 if daemon was already stopped
        #   2 if daemon could not be stopped
        #   other if a failure occurred
        start-stop-daemon --stop --quiet --retry=TERM/30/KILL/5
--pidfile $PIDFILE
        RETVAL="$?"
        [ "$RETVAL" = 2 ] && return 2

        # Many daemons don't delete their pidfiles when they exit.
        rm -f $PIDFILE
        return "$RETVAL"
}
