This works sometimes, and sometimes not. Perhaps it is one particular
server with a problem. I'll try to qualify that. The server which does
not serve NFS over TCP is a Solaris 2.6 machine.

AFAIK, this works (over NFS v3 and TCP) all the time without having to
specify any mount option.

When it works, the options do seem to be required. This seems to be
contrary to the mount_nfs man page, which states:
# The options are:
#
# -2      Use the NFS Version 2 protocol (the default is to try version 3
#         first then version 2).
#
Also, I thought NFS v3 implied the default use of TCP. But the man page
doesn't say. Thanks for the help.
