I don't agree with this. The access control rules are
fundamentally a property of the filesystem. Nobody expects msdosfs
or ntfs to have the same semantics as UFS, for instance.
Furthermore, even if you hacked up all the local filesystems to
support the "FreeBSD rules" (as a recent commit seems to have
done), you'd still get different semantics for remote NFS and AFS
mounts.
