Live Upgrade is encumbered code that cannot be released. I am told that the specifications for it are also encumbered and cannot be made available. To make things worse, zone installations seem to rely upon live upgrade code. Look around in the install-discuss and zones-discuss archives for details. A year or so back there was a specification for the next generation installer that would serve as a replacement for live upgrade or at least pave the way for a replacement. The Caiman installer seems to be the first part of this, but is quite short of being the bits to replace live upgrade. Take a look around in the Installation community (including install-discuss archives) and the Caiman project for details. If Indiana goes forth with ZFS as a core requirement, it could have the following impact to get around a lot of closed code: - lucreate, luinstall, luupgrade, and luactivate get replaced with utilities that manage snapshots, clones, boot environments, etc. in a ZFS-only world. - "zoneadm install" turns into much the same as lucreate, except that rather than being a global zone environment, it becomes a non-global zone environment. "zoneadm clone" already does (almost) this if the source zonepath is the root of a zfs file system. - flarcreate and friends could be improved to include data streams output from }zfs send". Incremental flash archives become fast to create because you can just send the diffs to the incremental flar. - Zones could then be created from flash archives that are designed to be global or non-global zones. Think of this like vmware appliance images.
