Let's not use .lnk as the extension, ok? It's an area that is still
quite sensitive <g>

So let's say that we use .!nk as the extension of our brand new symlink
implementation (assuming using '!' is ok).

Then here is how it would work:
 * if the user creates a symlink called "foo", we create a file called
"foo.!nk" on the underlying filesystem.
 * opendir+readdir does not return "foo.!nk" but instead returns "foo"
 * open("foo") opens the symlink, i.e. the VFS reads "foo.!nk" and open
the filename contained therein
 * create("bar.!nk") is not allowed: on such a filesystem, you are not
allowed to create any file ending with ".!nk"
 * symlink(...,"...very long name") fails if the filename is too long
for VFS to append ".!nk"
 * etc.

So there are definitely limitations but I believe it could work. I am
not going to argue that it should be done though as I am happy enough
with the current situation (and it's not like I have the time to work on
it either).
