You're right.  No upgrade mechanism yet supports zones (global or
non-global) on a ZFS root.  That's coming, but not yet.

The "fixed in Nevada a while ago" was the ability to do real upgrades
(both 'standard' and live) of Solaris systems with non-global zones
present.  A "real" upgrade consists essentially of computing the
differing sets of packages between the releases, and then doing
pkgrm/pkgadd in order to adjust the system upwards.

Extending that mechanism to Zones is what the project code-named
"Zulu" delivered.

Previously (in S10u1 through S10u3) the upgrade mechanism consisted of
some tricky patch-based work, from a project code-named "Ashanti."
The problem with that mechanism is that it required the distribution
medium (DVD-only) to carry the same bits twice -- once as packages
(for regular upgrades of global-zone-only systems) and then again as a
set of patches (for Ashanti upgrades of systems with non-global
zones).  It wasn't sustainable.
