bug#4902: 23.1; directory-abbrev-alist is not handled early enough

As the docstring of directory-abbrev-alist says:

   FROM and TO should be equivalent names, which refer to the
   same directory.

So the feature you want is not the feature provided by
directory-abbrev-alist :-(

Maybe we could change the code so as to expand the scope of
directory-abbrev-alist to include your situation, but I'm not actually
sure that's a good idea, because it doesn't seem clear exactly when that
rewrite should take place.

Maybe if you give us a bit more context to your problem, we can come up
with a better solution.
For starters explain to us: if the system doesn't have a "/mount"
directory, why does it show up in source files, email, and filemenu?
