Boot Pool Features

Two suggestions:

1) Make it easier to monitor the boot pool mirroring process. As far as I can tell, there is no notification when a second drive is added to the boot pool for the system to say "hey, I completed copying the primary boot drive to the mirrored one, your boot pool is now fully mirrored." There is no obvious progress bar either.

Is there a CLI command I could try to see if the two drives are now equivalent? i.e. carry the same files on them?

2) Consider allowing more than 2 drives to be added to the boot pool mirror. That would make it easier for folk to duplicate existing boot pool hard drives / USB sticks / SATADOMs for safekeeping / backup. Or perhaps offer a backup function that duplicates an existing boot drive to another attached drive.
