[Fedora-livecd-list] What is supposed to pull in a display manager?

[Bruno Wolff III]

I have been trying to get a games spin in shape and have been doing some
testing using F10 + updates + updates-testing.
I found in my tests that no display manager was getting pulled in resulting
in prefdm restarting enough times to get turned off and X never came up.
Adding gdm to the package list fixed this problem.
(On a related note, even after this something tried to run
gnome-power-manager which wasn't installed.)

Should the livecd-base kickstart include gdm or is there a better fix
for this issue?
