This seems to imply I can do something along the lines of:
lucreate -n newbe ...
for zone in $allzones ; do
zoneadm -z $zone halt
zoneadm -z $zone detach
done
luupgrade -t -n newbe -s /tmp/10_Recommended ...
luactivate newbe
init 6
for zone in $allzones ; do
zoneadm -z $zone attach -u
zoneadm -z $zone boot
done
But S10u4 adds support for live upgrade of zones, right? It doesn't
do it if I have ZFS in the mix. Since there is no mention of timeline
for live upgrade on a system with zones on ZFS (significant pain
point) this looks very promising.
