No, this is an upgrade from an F10 K12Linux install.  The script was
flaky there too, though occasionally it did complete successfully.
Maybe a timing issue or something?  I dunno.

I looked into the scripts some more and it appears the umount is not
being called directly in one of the LTSP scripts.  It appears it is
happening inside one of the python modules.  Great.

FWIW I did manage to reproduce the problem manually.  If I kill the
ltsp-build-client script after it has created the chroot but before it
barfs at the umount I can see that inside
/var/tmp/imgcreate-blah/install_root a bunch of sub directories are also
mounted.  If I try to umount /opt/ltsp/i386 it fails with the same
"busy" message as the script.  I think calling a lazy umount, or calling
it twice in a row would fix the issue.  I just don't know where to make
the change.  Any tips about how to find this bug would be great.

Alternatively, does anyone know what the ltsp-build-client script does
once all the packages are installed?  Maybe I can just manually do the
remaining steps.
