One thing to note, if you intend to create zpools / zfs-es on CURRENT which should be readable on STABLE, you must use the -o version=<x> parameter to create supported versions, i.e.: # zfs create -o version=1 ... # pool create -o version=6 ... This only applies to CURRENT, STABLE doesn't understand the 'version' parameter and will error out if you use it. Regards, -- Rink P.W.
