I'm with you. Snap Upgrade has a March deliverable for OpenSolaris,
which means that the widely deployed base (Solaris 10 and earlier)
won't see it for some time after that, at best.
If people find the use of zfs clones more important than live upgrade
(or upgrade, for that matter) search the zfs or zones lists from late
last year or early this year - I documented a manual procedure that is
essentially the following - there may be more details in the older
zoneadm -z master detach
zoneadm -z master attach
zonecfg -z newzone create -t master
# change IP's et. al.
zoneadm -z newzone attach
zoneadm -z newzone boot -s
zlogin newzone sys-unconfig
zoneadm -z newzone boot
zlogin -C newzone
