zfs discuss - Oct 2007 - Zone root on a ZFS filesystem and Cloning zones

Hi,

Does anyone have an update on the support of having a zones root on a
zfs filesystem with Solaris update 4?  The only information that I have
seen so far is that it was planned for late 2007 or early 2008.

Also I was hoping to use the snapshot and clone capabilities of zfs to
clone zones as a faster deployment method for new zones, is this
supported and if not when is it likely to be supported?

Thanks

Tony

No, they aren''t (i.e. zoneadm clone on S10u4 doesn''t use zfs
snapshots).

I have a workaround I''m about to blog, the gist of which  is

make the ''template'' zone on zfs
boot, configure, etc.
zonecfg -z template detach

zfs snapshot tank/zones/template at clean
zfs clone tank/zones/template at clean tank/zones/clone

zonecfg -z clone ''create -a /zones/clone''
zoneadm -z clone attach

Will post the URL once I pull my finger out.

I''m working on getting an answer to this.  We''re looking
at whether some of the changes to LiveUpgrade to enable
zfs boot can be broken out and delivered separately to enable
upgrade of zone roots on zfs.  I hope to have more answers
next week.
