Well, I'm slowly driving myself insane here :-)

With edubuntu-desktop installed I get a bunch of errors depending on the machine I boot.
 But mostly I have a problem with X not starting.  I pretty much have the same problem
with xubuntu-desktop installed as well.  It can't write the /root/.Xauthority file.  I
assume this is because the chroot is read only.  Is there a step missing in the wiki
about permission changes in the chroot to make this work?

If you have any other tips please let me know.
