For what it's worth, if I remember correctly, 4.3BSD was one of the major
contributions to SVR4. I suspect that if it hadn't been, nobody would've bought
it.
From what I've read, people bought SVRx for the
source code license, and then
bought the 4.xBSD for the reliability and usability.
And yes, it would be nice if the entire SysVRx source trees were released under
a suitable FOSS license; but I think the usefulness of such a gesture would be
in stymieing any future "The SCO Group" shenanigans, and I don't know that
such
acts of self-preservation are quite the flavour of the month with modern
software companies.

Hi,
I'm currently reading J. Lion's commentary of Unix Code Level Six.
It
is the most useful commentary to operating system
kernel I have ever
read.
It would be really useful to also have the source code of SVR4
kernel
for Intel x86. Does anyone have that?

https://minnie.tuhs.org/mailman/listinfo/tuhs OpenSolaris is derived from SVR4 and
much of the userland stuff is
still quite similar to the original release. Sadly, System V as a
whole is still regarded as a commercial product and no source is
available. If you want the source code for a decent early-90s Unix
implementation, I'd take a look at 4.4BSD. It's not SVR4, but it's
from the same era and has many of the same abilities.
