Do you have a backup of the machine you're trying to clone? I'd take that
ZFS snapshot and somehow get it written out to the test box rather than
trying to script it to be similar. Then you can either do rollbacks in ZFS
on the test box, or just cookie-cutter clone new test boxes in attempts to
get a successful upgrade process.
