ipkg zones not updated when updating release

[oxdrove]

Updating the release does not work for ipkg zones.
Using the instructions here:
https://omnios.org/upgrade
the packages are not fully updated on reattachment of the zone.

Workaround is to manually update the packages from the global zone after the zone attach
global# pkg -R /path/to/zone/root/ update -f -v

r151048 needs the zone attached, updated then attached again to get into a bootable state. As a minimum the documentation should explain the manual method but the fix is the zone to fully update on reattach.

This affects at least r151038 to r151046 and r151046 to r151048 which is 100% of those
tested so it probably affects all future releases.

Is there any prospect that this will be fixed in a timely manor? ie to allow LTS r151038 to be upgraded before it expires.
