Currently, if you disconnect and then reconnect again with a different set of
exported local drives, you have to manually run tl-mount-localdrives. This could
be eliminated by having some kind of "supervisor" daemon runnning in the
background, checking the availability of the NFS SSH tunnel. If the connection
is lost, and then back again, tl-mount-localdrives should be ran again. It would
even be possible to display some kind of GUI dialog for the user, and inform him
if he had some files open on the drive which doesn't exist any longer.
