Note, the box has been rebooted since I posted my last trace.

My box is Debian testing (recently updated).
# dpkg -l nfs-*
ii nfs-common 1:1.2.8-9 amd64 NFS support files common to clien
ii nfs-kernel-ser 1:1.2.8-9 amd64 support for NFS kernel server
same for both boxes.
nfsmount.conf doesn't exist on either box.
I'm assuming it is using nfs4.
Anything else I can provide?
