Just a follow up note - I cloned the drive using Clonezilla and the
LVM info didn't end up on the new drive.

Of course Clonezilla didn't reinstall Grub properly, and doesn't seem
to handle drive size changes very well either.

Back to seeing if I can get mondoarchive to work properly.  That's
where I started this smozzle, since mondoarchive wasn't handling my
loooong LVM naming convention.
