[install-discuss] Best way to upgrade a system with zone roots on ZFS?

[Ian Collins]

I'd like to (preferably live) upgrade my server from b62 to b72, but I
have a couple of possible show stoppers which I'm sure others have
encountered:

The system had identical boot drives, which confuses boisdev.  I can use
the replacement shell script workaround for that one I think (should the
script report all drives, or just the two boot drives?).

The system has zones with their root on ZFS.

Thanks,

Ian
