That was my original plan but I thought having information on whether a
device is shared or not could potentially be useful to other systems. If
not then you're right, it would be a lighter touch to add it only to the
'migrate' command.

I didn't realize drive-mirror + NBD was the preferred approach. Are
there any plans to drop support for the block/migration.c style?
