[gentoo-catalyst] updating configuration files and such on the livecd

[Caleb Cushing]

ok I need to put a custom gdm.conf and a custom firefox.js (not actual name)
on my livecd. what's the proper way to do this? also is there a proper way
to get firefox not to give me the "just updated screen" is there a way not
to get acroread to prompt me for a license agreement every time? it seems
running these from the livecd chroot should work... but I'm thinking there
might be a better way.
