Linked Image Zones
Starting with r151014, the ability to have
linked-image zones is available. In OmniOS, we chose to make
linked-images an option, available through the
lipkg brand zone. The
only difference between an ipkg zone (the normal zone type for OmniOS)
and lipkg zones is the linking of images.
A linked-image zone either has the same, or a superset, of publishers as the global zone has.
What are linked images?
r151014 through r151020
Linked images link the packages in a zone to the global zone. If you update the global zone’s packages, the linked-image zones get updated alongside it. This means going forward, an upgrade with linked image zones does not require detaching and reattaching the zone. You can update zones on a running system (at the cost of losing some log state during the time of the upgrade and the time of a reboot), or you can simply halt the zones, do the upgrade, and reboot with all linked-image zones automatically updated.

How do I use linked images with my zones?
Normal OmniOS zones are “ipkg” branded. To change a zone’s brand, you must detach it first, and then reattach it.
zoneadm -z <zonename> detach zonecfg -z <zonename> set brand=lipkg zoneadm -z <zonename> attach -u
Once the brand is changed,
