The best way to make sure your OS installs are repeatable and
non-deterministic is to script them. Here we use RHEL so we install
machines via kickstart. Previously I've used wrapper scripts to
'sysinstall' on FreeBSD and similar for Debian's installer (with lots of
help from its author). If you have your OS install procedure automated you
never have to worry about bare-metal restores. Just kick off the
re-install, then restore the unique data... you can even restore all of
/etc to the newly-installed box and it should work (modulo any changes to
fstab, ethernet devices, etc...)
