Disk labels are OK as long as they are unique across the company - or
alt least across the set of disks that could possibly ever be
connected to the same machine at once.  But that constraint makes them
hard to make up and remember.

I don't think ReaR should mess with that sort of thing.  It should be
a reasonable thing to do to migrate your system drive(s) from a system
on software raid to one on hardware or no raid, but move over one or
more of the software raid sets as-is, either in the copy or by
excluding them and moving the existing drives over.
