Go ahead! I have always wondered what was wrong with RFS, though I
suppose a Sun employee might have a slightly close perspective.

If people wish to discuss RFS vs NFS, I was there are Sun when all

Regardless of its technical merits (and I suspect that the
implementation may have been pretty bad) RFS was doomed by AT&T's
licensing policies and general ineptitude at marketing UNIX.
Similarly the widespread adoption of NFS was driven by the fact that
Sun made it a de facto standard. EDOTDOT caught my eye for some reason - maybe
because it's the only one
you attributed to linux in a long list of SVr1 ones... what were 72
through 76 in SVR1?
As the comment indicates, EDOTDOT came from "RFS" - the almost never used
"remote file system" that was (optionally, I think) part of System V Release
3.
As best I can recall, that is also where several of the other error numbers
in the 72 - 79 range probably came from.
I also looked up EDOTDOT and found reference to RFS but not much info about
it. Why was it not used? Not reliable enough? I have often thought that
the stateless, idempotent NFS protocol leaves a lot to be desired due to its
inability to implement unix semantics (as discussed in the wikipedia stub
article on RFS), has this been improved with NFS4? Should RFS be revived
and used? Some of its features sounded quite attractive (location
transparency, etc). It does appear to have the ability to execute a program
remotely?? What happens with regard to PIDs, home directory etc in this
case? Does anyone know?
