Different setup (see below), plus they delegate control the zone for the filesystem. zonecfg -z zone add dataset set name=zones/data/zone set alias=zone-data end vs zonecfg -z zone add fs set type=zfs set special=zones/data/zone set dir=/export/shared end or zonecfg -z zone add fs set type=lofs set special=/zones/data/zone set dir=/export/shared end Nicholas ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
