Provided NFS doesn't repeat XIDs at boot (which it used to when the
kernel had no idea what the TOD is.)
I believe the NFS standard allows NFS servers to repeat their response
to a repeated XID even if the request is different... which used to
cause chaos for me with a machine that has no RTC and boots using NFS
root. So just be aware that if the NFS XID is still dependent on TOD,
then not having RTCs loaded can cause chaos.
