That's what I did with the snv_93 UFS BE I had still around, with the
exception that I used zpool import -f -R /mnt to avoid pathname clashes
between the miniroot and the imported pool. I think I even exported the
pool afterwards, but I'm no longer certain about this: I seem to remember
problems with exported root pools being no longer bootable.
