copy of that source but so far as I know it's locked up.
Note that
the Svr4 kernel was derived from the SunOS-4.0 kernel.
I was in the kernel group at Sun at the time. The pictures I posted

In no way was SVr4 even remotely derived from the SunOS 4.0 kernel. SVr4 and Solaris kernel code is very similar.
Sure it's similar. The process was:
untar the SVr4 code
take anything useful from the SunOS code
try and make it compat
If you want to call that derived from that's your call. In my mind "derived
from" would mean start with the SunOS code and make it SVr4 compat. That
is *not* what AT&T paid $200M to have happen. They knew that System V was
a non-starter and they wanted all the SunOS goodness in System V.
