I do not care, since I only match on the model type of the disk, not
exactly which disk. You could use the serial number, or use the
by-path directory.

I do not know. But I'm pretty sure that md uses some uuid on the
partitions of the disks to assembly the md device.

Yes. IIRC internally we convert everything to blocks.

Yes, hooks always do the trick ;-)

I guess it would be fine if you could publish your zfs hooks here on
the list. Others may be interested in them.
