       I
write this on a Linux machine, and I love the operating system.
 Linux is a work-alike of UNIX, developed by Bell Labs (K&R).  The 
 Apple
 OS-X is a licensed variant of UNIX.  Linux is NOT an offshoot of 
 Apple. 
    OK, I know this is way OT, but I'd like to see that documented.  As
 far as I know OS X is NOT a licensed UNIX.  As a matter of fact, by 
 any
 definition I'd use, it's not unix period.  It just has a really pretty
 [and incredibly useful] POSIX API. 
 AFAIK, it's Mach with a POSIX layer and a FreeBSD userland, and of 
 course
 Apple's custom stuff bolted on.

Depends on what you mean- I think I recall the Open Group finally got 
Apple to certify it under threat, but Sys10 has never had a AT&T 
license AFAIK.

OTOH OSF/1|Tru64|DIGITAL UNIX has a very similar structure, and no one 
argues the UNIXness of that beast (except for those who also argue 
against AIX).
