chrooting

[Travis Newman]

I'm trying to figure out how to chroot into other distributions, and so 
far I'm doing pretty well. I have Debain Sid (starting there because 
that's where what little documentation I found was using) in /sid and I 
can chroot into it and use it at the CLI til the cows come home. I have 
my /etc/inittab set up so that vt6 is Sid, so I don't have to log in, 
chroot, etc. It's already there. Now here's the weird part. GDM doesn't 
work at all with Sid, though I can use startx (and get a 
gnome-settings-daemon error every time). But if I kill gdm in Ubuntu, 
startx in Sid, then restart GDM in Ubuntu, it automatically changes VTs 
so that I can have them both going at once. I'm not sure if you can make 
the startx command do this or not, but anyway... What I'd like to do is 
be able to start Ubuntu and let it start GDM, and be able to start the 
Sid (or whatever) GDM or startx and have it go to another VT. Or 
ideally, for Ubuntu's GDM to autostart on VT7, Sid's to autostart on 
VT8, etc, but I don't know if that's possible. At this point, I'll 
settle for having to start it manually. The documentation I was using 
says this is possible, but I can't get it to work. Does anyone have any 
insight into the situation? I'm looking to eventually tweak different 
distros or versions of distros for different tasks and have them running 
on different VTs maybe, but I'm really just trying to learn the 
possibilities and tweak the crap out of my PC.

Here's the documentation I was talking about:

And I apologize for those of you who are also on the forums and have 
already read about this.
