See bug 10160 for the example ACLs. On zfs, as seen in 3.6.18 with the patch from bug #9467 but still the same in master. I'm confused as to why we only map @owner and @group to the current owner and group, not CREATOR OWNER. We only do it for inherited ACLs.
Alexander, Can you remind me a bit more about why we chose to do it this way? Thanks,
