I currently have a USB disk drive on a machine in my garage which I
use for backups.  Currently I access this as follows:-

    It's mounted locally on the garage system.

    It's NFS exported from the garage system.

    It's NFS mounted on my desktop system.

While this works it's not 100% satisfactory because firstly it's a
*bit* difficult to guarantee that the mount of the USB drive on the
garage system happens automatically when it powers up.  Secondly if
the garage system powers down and then up again I get the dreaded
"Stale NFS File Handle" on my desktop system and it's a real pig to
clear that and get the mounts working again.

If I could 'see' the drive on my desktop system as a USB drive then I
could mount it there on an 'as needed' basis (i.e. when the backup
cron job does a backup) and I would need NFS.

I've just had a "lateral thinking" thought, it might be that sshfs
would be more robust than NFS for this sort of use.
