Alan,
Would you please put the following patch into 2.0.3x? I run an NFS
daemon for accessing my tape drive on a non-standard RPC
program/version so it does not interfere with standard NFS usage.
Once this is in the kernel I will submit the corresponding mount patch
to Andries again.
Joe Buehler
This is a patch to the linux kernel to enable it to mount NFS servers
running on non-standard RPC program/version numbers.
It has been tested with 2.0.33 and 2.0.34.
