Re: Understanding the kernel

Quoting James Buchanan (softwaredev@dodo.com.au):

The book described the architecture of the kernel. While some of the modules have changed, there's been new paint, a couple walls have been knocked down and metaphor straining changes have been made, the architecture is about the same. So it's a map rather than a document that describes the modules.

NetBSD and 386BSD were always separate, AFAIR. NetBSD came from Net-2 and everyone added 4.4BSD-lite when it finally got freed. It ran on Suns (non-386) very very early on because 286's were around at the same time as Sun 3s.

FreeBSD (nee 386BSD?) was a separate effort by Bill Jolitz.
