Hardware, Embedded Systems IDC's newest survey of server vendors shows boxes running every kind of operating system -- except Unix -- sold more during the last three months of 2010. Sales of Linux servers rose 29 percent; Windows rose 16.8 percent, but most surprisingly, sales of mainframes shot up 69 percent " the highest growth rate IDC ever found on mainframes.

Linux is a clean-room clone of Minix. There was never any UNIX code in Linux. It's is the bastard step-child of UNIX' distant cousin Minix. No actual blood relation; no actual code history.

BSD is a continuation of AT&T UNIX source code, with a bunch of extra features added in. By the year 1992, there was no original AT&T UNIX code in BSD anymore, but the history is still there, and you can trace back through the CVS commit logs back to the original UNIX sources.

While none of the free implementations of BSD have paid the exorbitant fees to go through the certification process and thus none can call themselves UNIX(tm), they are most definitely Unix-based systems.

MacOS X is a crazy hibrid of NeXT, FreeBSD, NetBSD, and Mach, giving it direct links into the UNIX source code lineage. And, Apple has paid for specific versions to go through the certification process. Thus, it is also UNIX(tm).

But there is no way, no how, none possible, for Linux to be considered UNIX(tm), or even Unix-based, or even Unix-compatible.
