start a live-cd with gnome-classic session

[Émile CARRY <emile.carry@sequanux.org>]

Hi,

I try to generate a live-cd that start with a gnome-classic (or 
gnome-fallback) session for our student to match our lab. I generate 
live-cd of wheezy with version 3.0.5-1

I did not find hint in list archives.

Is that possible by modifying a configuration file of gdm or I must use 
dconf? and how? a hook?


Have a nice day.
