Yes, it is. SVR3 memory management was based on "regions" a la VMS; SVR4's VM is a page-based system based on SunOS's approach. -|Its network base is entirely different, -What do you mean by "entirely"? I'll be really unhappy if it only -talks to other sysV machines. I mean that BSD's fundamental networking mechanism is the "socket" while SVR4's is based on streams. The word "base", and especially the mention of "r-commands", should indicate that I wasn't talking about global protocols. TCP/IP, UDP, etc. are supposed to be supported in addition to the usual AT&T-specific facilities. -What I'd really like to know is if there are any publications which -describe what's new and what's changed in sVr4. I'm not sure I should volunteer this information, but the title foil for the "SVR4 Overview" from the Baltimore USENIX conference presentation had Marilyn Partel's name on it (mar@attunix.att.com). Perhaps she can send you the complete information packet as handed out in Baltimore, or tell you where you can get it.
