I should note that I tried to be the "good guy" and just
fix it myself,
however fixing that led to another problem where the initial chroot
created was too small, fixing that led to the whole thing being
oversized and invalid for mkisofs. That was the final straw.
Coincidentally I was playing with it a bit with Rakesh (CC'ed) and we
also hit the same blockade about the small chroot. Maybe Rakesh went a
bit further.
