zfs discuss - Dec 2006 - Why root zone can''t be on ZFS for upgrade ?

Hi,

Something is unclear in "Solaris containers" and "Solaris
ZFS" docs

Two extracts :

http://docs.sun.com/app/docs/doc/819-5461/6n7ht6qsm?q=zone&a=view
"Consider the following interactions when working with ZFS on a system with
Solaris zones installed:

A ZFS file system that is added to a non-global zone must have its mountpoint
property set to legacy.

A ZFS file system cannot serve as zone root because of issues with the Solaris
upgrade process. Do not include any system-related software that is accessed by
the patch or upgrade process in a ZFS file system that is delegated to a
non-global zone."
http://docs.sun.com/app/docs/doc/817-1592/6mhahuop2?a=view
"4. Set the zone path, /export/home/my-zone in this procedure.
               zonecfg:my-zone> set zonepath=/export/home/my-zone
Do not place the zonepath on ZFS for this release."

I can''t understand why the upgrade process need to have non-global root
zone on anything else than zfs.      Does the boot cdrom can''t mount
ZFS volumes ?

  Thanks Jeff.  

  Any idea on when Install Software will be able to "see" zfs vol ?
