Thanks, I'll merge that a bit later.

First though, I've just tried to adapt it to also work for Linux. I
also replaced your function with a substitution which I think should
do the same thing so I would appreciate if you could check that the
updated function below still works.

I don't suppose that $OSTYPE on FreeBSD includes any of the FreeBSD
version. It is just that it is a tiny bit faster to check than
`uname -sr`?

If `sysctl -A' or `sysctl -aN' is run as a non-root user, do you get
any output to stderr (you do on Linux)? If so, we need to add a
redirection.

Does anyone on zsh-workers mind if I put this on the stable branch.
Mainly because I suspect the FreeBSD folks would otherwise be
maintaining it as a patch for their port.
