The Ubuntu installation inside the chroot.

I added 'set -x' to all of the scripts and there is no additional
output. This seems very bizarre.

-v didn't show anything, so attachment 'schroot-debug' is the output
of running (as root) schroot --debug=notice -c precise mount, modified
carefully to remove only the other chroots and the host environment

Incidentally I purged schroot's config and the reinstalled the
jessie/sid version before running this (keeping only my choots and
custom profile).
