I don't think Jerry will be able to do so, because there is no set of
"latest ACL standards" defined.  The closest thing to an actual standard
outside of the NFS standard is the abandoned standard for POSIX.1e ACLs,
so far as I'm aware.  Meanwhile, for Linux-based systems, there is also
only an experimental implementation of the NFSv4 ACLs (as your quote
points out).  Perhaps Jerry thinks that AIX, MacOS X, or Solaris is The
Best Unix, or perhaps he simply is not aware of the actual state of
things in the world of ACLs.

I suppose it's possible that I'm ignorant of some important detail,
instead.  If so, I hope someone will educate me on the subject.
