You must choose a name for your zone. If you do not specify the path, the default value of zonepath is /system/zones/zonename.
If you choose a name and a path for your zone, the zone must reside on a ZFS dataset. The ZFS dataset will be created automatically when the zone is installed or attached. If a ZFS dataset cannot be created, the zone will not install or attach. Note that the parent directory of the zone path must also be a dataset.
If the path is not specified, the default value of zonepath is /system/zones/zonename.
