I would strongly discourage the use of sshfs for the name dir. For one, it's
slow, and for two, I've sen it have some really weird semantics where it's
doing write-back caching.

Just take a look at its manpage and you should get scared about using it for
a critical mount point like this.

A soft interruptable NFS mount is a much safer bet.
