As I recall, RFS was implemented over virtual
circuits, whereas NFS was
over datagrams (UDP). RFS was well suited to Datakit, which only did
virtual circuits, and they often were used together inside Bell Labs.
One of the reasons NFS won is that IP won over Datakit.
I think another reason is that AT&T got a lot more, er, "difficult"
about its licensing come SVR3, which introduced RFS. Many of the major
UNIX vendors (IBM, DEC, HP) didn't bother to license it. As most of them
already had NFS, it wasn't worth the trouble.
SunOS 4.0 had RFS. I think early versions of 4.1 did, but I'm pretty
sure that by 4.1.3 SunOS had removed it.
