The example you mention of Tru64 UNIX is not BSD or SysV. It is based on OSF/1 which was, in turn, based on mach. It was designed to look like either BSD or SysV, depending on what you preferred, although to get a real SysV flavor you need to add the SysV licensed products package to get things like sar. But I've been told that with this package, it is almost indistinguishable from SysV. Darwin and MacOS X are also based on a Mach kernel, but have only a BSD environment around the kernel. R.
