Following a suggestion in the Arch Linux Wiki:
I made this minor edit to /etc/exports on weather (the server)

Old /etc/exports:
        /               amito(rw,no_root_squash)
        /home/jonrysh   amito(rw,no_root_squash) 
New /etc/exports:
        /               amito(rw,fsid=0,no_root_squash)
        /home/jonrysh   amito(rw,no_root_squash)
Note that the addition of "fsid=0" to the entry for the root directory
allows *both* the root and a directory under it to be exported.  To
understand this better, read the following section in the Arch Linux
Wiki: Exporting directories outside your NFS root

All very subtle, and undocumented.
