It's the "sticky" bit.  Originally, it was used for executables, it told
older versions of UNIX to save the text segment of the program in the
swap space as long as possible; this was a way to increase the
performance of system utilities that were run very often, like sh and
ls.  On a directory, it tells the system to only allow the owner of a
file to delete it, very important for tmp directories.

I do mine in /etc/rc.local, which is the equivalent of
/usr/local/etc/rc.d.  Here's the line I use:

	echo -n 'starting local daemons:'

	# put your local stuff here

	/usr/X11R6/bin/xdm && echo -n ' xdm'

Pretty straightforward stuff.
