I suspect that making live upgrade work within a zone would be significantly easier if ZFS was a prerequisite. It looks as though the ipkg brand already has support for mounting the appropriate dataset on boot and attach. Delegated datasets can be snapshotted and cloned within the non-global zone. It seems as though the only missing bits (without having read the LU code) are: - Live Upgrade shouldn't try to read or update OBP through PICL or otherwise - The brand needs to trick live upgrade into thinking that it is in the global zone I don't care so much if Live Upgrade or something else is chosen, I just see the lack of a live upgrade work-alike as a potential blocker to adoption. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
