H.J. and Allen:
While you are at it, here's a fix for a long-time annoyance. I have an eclectic collection of older boxes, including a DEC VAXStation 3100 which must NFS boot from a Linux server. This is the machine which requires an exported file for swap - my motivation for bringing it up on the list to begin with.
The VAX would never boot from a 2.1.x system, so I traditionally brought up 2.0.3x when I needed to run it. Since your patch theoretically made the swap available, I spent some time digging into the boot failures.
Turns out that kmountd tells the portmapper it's able to provide NFS v3 services. This is all fine and well, but the client (naturally) assumes that the nfsd can do the same - which it cannot. This quick patch corrects the problem (although a reboot is required to clear V3 from the rpcinfo list - why?) and permits my elderly Vaxen to run :-). Now, if I could just convince 'mopd' to respond to boot requests without having to turn on promiscuous mode on the network adapter... But that's another subject.
I'd argue that we should not be advertising NFS3 services for any of the RPC daemons until such time as the NFS server actually speaks it.
Opinions?
Steve
