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.
