Zone update on attach functionality

If you’ve used the zone migration features (e.g., attach and detach) in Solaris, you may have bumped into issues when you tried to migrate a zone from one machine to another, and the servers didn’t have the same set of patches or packages installed. With Jerry’s putback of PSARC 2007/621 into opensolaris, this should be a thing of the past. Here are the bugs that were addressed by PSARC 2007/621:

PSARC 2007/621 zone update on attach
6480464 RFE: zoneadm attach should patch/update the zone to the new hosts level
6576592 RFE: zoneadm detach/attach should work between sun4u and sun4v architecture
6637869 zone attach doesn’t handle obsolete patches correctly

Thanks Jerry for this super super useful feature!

  1. Patch syncing between hosts has been really irritating when migrating zones.

    Hopefully this work will accelerate the zones HA projects.
