Funny, I had thought that OSF/1 was based on Mach and the
4.3BSD superstructure atop the Mach kernel. Its reason for
existence is to provide an alternative to System V.
As for AIX being a SysV derivative, that's news to me, too:
AIX 1.x for PS/2s and AIX/370 were developed from BSD; AIX
3.x for the RS/6000 has as many BSD roots as SysV roots,
and its programming interface is more POSIX.1 than it is
either SysV or BSD; AIX/ESA (the successor to AIX/370) is
another OSF/1 port.

True enough. The System V PROGRAMMING INTERFACE is,
however, the de facto standard. Most of the vendors who
maintain their own OSs instead of porting each new
version from USL are keeping their systems SVID compilant,
whether the kernel technology is derived from BSD or
pre-SVR3 AT&T.
