It is a copyrighted work which is freely redistributable. b) BSD/OS and FreeBSD are both based in 4.4BSD-Lite. Neither contain that awful AT&T-tained code. The reason which BSD/OS is not freely redistributable is that BSDI has rewritten or written from scratch many pieces of the BSD/OS system. They consider those pieces proprietary software. On the other hand, those with a BSD/OS source license will see many files that carry the same or similar copyright notice and/or licencing terms as similar files in FreeBSD or NetBSD. Files which contain "UCB-style" (a.k.a. the style used in 4.4BSD-Lite) licencing are redistributable. Others refer to a BSDI licencing agreement which states quite clearly the terms under which that code is provided. -- Jason R.
