The utilities in 2.0 for running NFS client work fine with the 2.1 NFS client
AFAIK. But you may need to change the startup script to start portmap before any
NFS mounts.

A number of people have reported slow operation when a Linux client talks to a
Solaris server, but Linux talking to knfsd is quite fast as long as you make
writes async.
