Because one of my non-global zones is the router, yes, this would have to be
the case. (Either that, or I plug in my global zone to the Internet
directly, bypassing the NAT/FW zone until such time as it's upgraded.)

I know little about this technology. A wild, uneducated guess would be:
At the beginning of "pkg image-update":
- Foreach ipkg zone
* Find packages that aren't ALREADY in the global zone.
* Add these to the list to be updated.
Proceed with contacting the repository, grabbing EVERY PACKAGE
needed.
Install global's newest packages in its new BE.
Install every ipkg zone's newest packages in the new BE.

I plan to only update to latest/greatest (after all, besides being my home
server, this is yet-another-instance of eating-my-own-dogfood), so this might
work nicely.
In fact, this workaround/suggestion inspired my above shot in the dark about
what to do.

Yes, even when one of the non-global zones is forwarding the packets into the
global zone! :)

Modulo quick backups, I may wish to volunteer for testing this.
Thank you!!!
