Like I said, in 1992 or 1993, I had a BSD licensed SunOS 4.1.something,
I think 4.1.3, kernel. No STREAMS, no RFS, no STREAMS based tty drivers,
it was what lots of people called SunOS: "A bugfixed and improved BSD".
I shopped it around inside Sun and there were plenty of people who wanted
a reason to say it wasn't open source ready and they couldn't find one.

And I ripped out RFS. There was more than 1.1 versions in some version
of SunOS, my former office mate, Howard Chartok, did a pile of work on
RFS.
The networking stack in SunOS 4.x was BSD
derived. You might be thinking
of Solaris, that took the Lachman STREAMS stack but that was 5.x, not
4.x.
I was thinking of the streams stuff that's in 4.x BSD. There's AT&T
copyrights
on it. There's also, strangely, rfs sources included with some of the stuff
one
can find online. But it looks to be imported nearly verbatim from System V
of some flavor with very few edits, judging by the 1.1 versions in many of
the
files. As the only
guy, that I'm aware of, who took all the encumbered stuff
out of the kernel, put back the BSD tty drivers and a few other small
things that resulted in a kernel that we could freely open source,

I'm just reporting what my VP told me... Grepping through the source I can
find online, the evidence is closer to what you say than what Glen told me.
Either he or I must have confused Solaris 2 with SunOS 4.
