DiskImage.imageBuilt has broken and no longer runs the finalization properties that get added to the chroot. This includes installing grub, and Chroot.noServices etc.
Seems that the _chroot info that gets propigated from imageBuilt is
for the chroot before those properties are added to it. Then when chaining
into the chroot, _chroot info is examined to find the properties to
ensure.
I have not yet been able to determine what broke it -- I'm sure it used to work. --Joey
