I suspect that if it hadn't been, nobody would've bought it. My understanding had been that BSD and SysV were quite distinct and that BSD forked off around the early research editions (V6 or V7?), if indeed 4.3BSD was a major contributor to SVR4 then it would have been in a few specific areas, e.g. the sockets code, because SysV had its own competing idea called STREAMS that I believe was later discarded (or not used much) when the BSD sockets API became the de facto standard. Also as I understand it, SunOS was a BSD which had heaps of development and original ideas put into it (shared libraries I think is one example), but was discarded as a political decision because AT&T had managed to convince most corporate customers that BSD was merely a hack and SysV was the "real unix", so Sun decided to create Solaris instead by licensing SysV as a starting point, I may have things slightly backward so I would appreciate if anyone can confirm this? cheers, Nick > 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. > > Wesley Parish > > Quoting Michael Kerpan : > >> On Mon, Jul 11, 2011 at 6:29 AM, Michele Ghisolfo >> wrote: >> >  Hi, >> > >> >  I'm currently reading J.
