Perhaps there's some confusion with OS X. :-) OS X started life as NEXTSTEP, using the CMU Mach 2.0 kernel written by Avie Tenavian and a BSD-4.3_reno userland, heavily influenced by SunOS 3/4. Since NEXTSTEP, Apple has updated the BSD layer to 4.4Lite and included changes derived from FreeBSD, OpenBSD, and NetBSD-- but mostly the latter, at least at the time I was looking. Certainly it's false to claim that OS X started as FreeBSD. -- -Chuck
