   I don't think that having different partitioning schemes is a
problem for an LVM. Whatever the partitioning scheme, you would
simply have a single "NetBSD LVM" partition which goes into the
pool with the LVM partitions on the other disks. The traditional
disklabel then goes away (or is constructed automatically to reflect
the partitioning scheme, but not used for the LVM pieces) to be
replaced with a more complicated but more flexible LVM scheme built
on top of "NetBSD LVM" partitions.
