I was thinking more something like:
- find all disk devices and slices that have ZFS pools on them
- show users the devices and pool names (and UUIDs and device paths in
case of conflicts)
- let the user pick one.
- in the case that the user wants to initialize a drive to be a backup
you need something more complex.
- one possibility is to tell the user when to attach the desired
backup device, in which case the GUI can detect the addition and
then it knows that that's the device to use (but be careful to
check that the user also owns the device so that you don't pick
the wrong one on multi-seat systems)
- another is to be much smarter about mapping topology to physical
slots and present a picture to the user that makes sense to the
user, so the user can click on the device they want. This is much
harder.
