The short answer is that for a bare metal restore, I first install a stock
OS, then use BackupPC_tarCreate, restore everything to a directory, then
use the recovery console to rotate it into place.  After a reboot,
everything's back, including the registry.

Naturally, I do lose ACLs and whatnot, but aside from a few tweaks, the
process at least works.  I've been considering adding a supplemental ACL
backup to the routine.
