[gentoo-catalyst] Using xdm as display manager in live cd

[Tom Stellard]

I am trying to build a live cd using xdm as the display manager instead
of gdm.  I am running into a problem, because xdm does not automatically
log you in after 10 seconds like gdm.  Instead, xdm asks for a username
and password.  I have tried user: gentoo with no password, but that does
not work.  Is there a username/password combo that I can use here, or do I
need to modify one of the scripts to create a user prior to starting xdm?
