Nope, it's just mundane packet loss. For some reason, about half of all
mount attempts just get lost. If I run tcpdump on both ends, when the
mount fails, the client sends two packets right away, and two more a while
later, and none of them get through to the other side. It doesn't appear
to ever recover - but if I restart it, it sometimes works.
No packets other than NFS mount and unmount requests are staying lost.
*sigh*.
It appears that "mount_nfs -T" still implies udp for the mount protocol
itself. I don't suppose there's a way to override this?
