Actually, with ZFS root/boot support, rollback is pretty trivial. I'm not
sure if the package tools integrate it directly, but you could always
create a new boot environment (utilizing ZFS clones), update packages into
it, then boot it.  If things don't work out, simply change your active boot
environment to the original one, reboot, and bing, back where you started.
