BSD-style is more "anti-SVR4" style, but you also need to remember that everyone working on linux ps in 1991 had years of experience with BSD 4.3 and SunOS 4; the post-reno liberated BSDs (386, Free, Net, and a dozen others that only lasted a year or two) aren't really relevant to that use of the term.
I don't need to have false memory syndrome, thank you. (-:
Michael K. Johnson was an undergraduate at St. Olaf College at the time, simply not old enough to have had "years of experience" with commercial Unices. The reality is that this was not written by a bunch of old hands with tonnes of professional Unix experience. Branko Lankester was at the University of Amsterdam.
