I believe the author's current setup is running ZFS on Illumos (specifically OmniOS), with volumes exported over NFSv3 and Samba. It's not mentioned in this post, but some of the older ones talk about it [1]. The comment about FreeBSD was worrying that if they started relying on ACLs now, and later switched their fileservers to NFS-on-ZFS-on-FreeBSD instead, they might end up with incompatibilities in the ACL models.
