Keep in mind that RFS was never designed to be used in an OS-wise hetero-
geneous environment.  AT&T intended it to be run in an AT&T SVRx environment
and damn the torpedoes.

I think this was fortuitous happenstance.  SVR4 was the first System V
to begin to catch up with the rest of the UNIX world (remember:  most
sites that used networking were, for a LONG time, based on Berkeley-style
systems -- including the Berkeley FFS.  SVR4 finally caught on to this
and used it.)  There were hybrid extensions (UniSoft UniPlus+) which
were SVR[23] with NFS and NIS glued on, but...

NetBSD: true inheritors of the UNIX(tm) legacy.
