I think the OS would best be characterized as SVR2 with the addition
of the 4.1bsd VM system ("real" SVR2 had no demand paged VM) and the
further addition of its own unique approach to shared libraries.
Yes - it is an SVR2 derivative - essentially the same thing that CT used
on their "MiniFrame"
systems (some of the header files in /usr/include/sys actually contain
references to the MiniFrame)
