I see I somehow managed to drop the mention of the name, though. I've fixed it now with a better description of where it fits in. Let me know if that's enough. > Somewhat related: A reason to use BSD would be that you want to > develop a product based on a system, and may not want to use a > completely open source model. Good one. I've added that as well, as well as a brief discussion of the main difference. > At some point, you may want to point to "bsd.com", which will eventually be > something of a BSD, Inc., page for BSD info.

A lot of the code in BSD is also in System V, and Research UNIX editions 8 to 10 were derived from 4.1cBSD.

There's a perception in the Linux world that the BSD projects are fragmented and belligerent, and I don't want to help that perception at all. Just enough to explain why there are so many.
