Hi Adam, There are actually a lot of BSD-derived operating systems that are, in fact, not BSD licensed. The current state of BSD licensing seems to be "here's the source, do with it what you want". Many folks have used BSD-licensed code in closed source products: - Juniper uses FreeBSD as the foundation of their JUNOS for their routers - Apple uses BSD in duuuh :) - Several firewall vendors use *BSD in their internet appliances - Microsoft apparently uses a lot of FreeBSD networking code in Windows 2000 While this may or may not be considered to be "stealing" by GPL advocates (FTR, I like the GPL), for folks who favor the BSD license, it's all a part of life's plan.
From what I have seen in my code browsings the BSD licenses are intact in
the appropriate places in the Darwin source code. For a random example, take a look at /usr/include/signal.h. Hope that helps, Jacob On 4/24/02 9:40 AM, "Adam Atlas" <houou@mac.com> wrote:
It seems that Darwin is one of the few (the only?) BSD-derived
operating system that does not use the BSD License. I downloaded the
4.4BSD-Lite sources (Darwin is based on 4.4BSD-Lite, right?) and it
comes with a copy of the BSD License. And the BSD License says that any
product derived from it, in source or binary form, must include that
license. How did Apple get around that?
I though 4.4BSD-Lite was in the public domain, but I guess I'm wrong.
