   That does not work because if the destnation is a directory it will
   try to link in the destination directory... (I tried). This is why
   I suggested that it needs to be done differently.

ln -sfh?

As an aside, it would be nice if there were an easy way to create a
symlink at a temporary location and rename it over the permanent one.
`ln -sfh' will unlink instead, and mv(1) is too smart for its own good
about directories to be able to rename over a symlink reliably...
