Beware of confusion.
There is the 8th and 9th edition remote file protocol
(I have papers somewhere I think), by Weinberger.
This evolved into 9p, Plan9’s file protocol.
There is also RFS, I think a USG package for SYSVr3. The paper I have
About this is by Author L Sabsevitz, though I don’t know if he was the author
of the code, or just the paper.
They are rather different beasts with similar names.

The nice idea in RFS was that it supported remote

had a concept like XDR for ioctls.
I believe it did not.
The funny thing: RFS was supported in SunOS4, but
not in SunOS-5.
And Howard Chartok was ecstatic over that decision (he was my office
mate and did the port into SunOS 4.x. Not one of his favorite projects.)
