Hello, I surely did a mistake by configuring our zones with zfs-root: Patches are no longer possible (without disabling the zones in /etc/zones/index) in S10u3! My questions are: 1. Has S10u4 support for zone-root in zfs? 2. Will it be possible to patch my _existing_ zfs-rooted zones when such zones will be supported? 3. Sun itself seems to recommend zfs for zone-root for easy cloning of zones! I''m somewhat confused; Can someone give me a hint how I should/could update our servers to an actual patchlevel (OK, this is somewhat Solaris-specific, but it depends on how zfs-zones are handled by the process of updating)? Thanks Jan Dreyer
