Switch the default NFS mount mode from UDP to TCP. UDP mounts are a
historical relic, and are no longer appropriate for either LAN or WAN
mounting. At modern (gigabit and 10 gigabit) LAN speeds packet loss
from socket buffer fill events is common, and sequence numbers wrap
quickly enough that data corruption is possible. TCP solves both of
these problems without imposing significant overhead.
