Yes, the code already does this when you run "zoneadm attach". >> For the case you describe though, the easy thing >> to do is just snap off a zone clone and update that. >> > Ehrm, for some value of easy - cloning is probably not a problem if you > happen to have things on zfs, but that's not for everyone (and not > supported by Sun last time I checked) Zone cloning works even without zfs. It is faster and cheaper with zfs but is still pretty good on UFS. In general I would think you will always want a backup of the zone when you "update on attach"; either by leaving the old zone on the original system or by cloning. That way you can fall back if you see a problem on the updated zone. This is a similar philosophy to live-upgrade and just seems like the right way to do it.
