saves a backup copy of it in the last sector of the disk.
This looks like layering issue to me.

In theory, both gmirror and gpt should work on 'providers'. So if you give an gmirrored provider to gpt it should touch the last sector of the gmirror, but not the last sector of the disk - and not complain. It should not even be able to see the last sector of the real disk.

Is this hard to fix?
