Another potential difference ... I have been told by Oracle Support
(but have not yet confirmed) that just running the latest zfs code
(Solaris 10U10) will disable the aclmode property, even if you do not
upgrade the zpool version beyond 22. I expect to test this next week,
as we _need_ ACLs to work for our data.
