System Resources Enhancements

The following system resources features and enhancements have been added to the Solaris 10 5/09 release.

Support Added for Using ZFS Clones When Cloning a Zone

If the source and the target zonepaths reside on ZFS and both are in the same pool, a snapshot of the source zonepath is taken and the zoneadm clone uses ZFS to clone the zone.

You can specify to copy a ZFS zonepath instead of specifying to clone the ZFS. If neither the source nor the target zonepath is on ZFS, or if one is on ZFS and the other is not on ZFS, the clone process uses the existing copy technique.

In all cases, the system copies the data from a source zonepath to a target zonepath if using a ZFS clone is not possible.

zoneadm attach -b Option

Use the -b option to specify official or Interim Diagnostics Relief (IDR) patches, to be backed out of a zone during the attach. This option applies only to zone brands that use SVr4 packaging.
