For comparison:
RHEL4 and RH9:
inittab:
# Run xdm in runlevel 5
x:5:respawn:/etc/X11/prefdm -nodaemon
SuSE SLES-8 (AMD64) (8.1):

==================
The drawback to the inittab method is that there is easy way to abort
it. The only way I can think of is to C-A-F1, log in and edit inittab
to comment out the respawn line, and run `inittab q`.
With the startup script, you only need to `/etc/init.d/xdm stop`.
There are advantages and disadvantages to both methods.
However, I'm not sure my opinion should count here as I don't like ?dm
at all. I always start at run level 3 and do startx.
