If you attended any of the SVR4 presentations, such as the AT&T BOF at the Baltimore Usenix, it would have been quite apparent that the SVR4 implementation has little in common with BSD, other than a common 7th Edition UNIX heritage. Its memory management, like SunOS's, is entirely different. Its character I/O system is entirely different. Its general filesystem support is entirely different (although one module does support BSD filesystems as a special case). Its network base is entirely different, although some of the "r-commands" may have been adapted from BSD versions. And in general it makes the current BSD release look sick.
