So this is (arguably) a bug in febootstrap, although it might be
easier to fix it by removing the empty /lib directory from the ntfs-3g
package.

The code in general is designed to deal with the case where multiple
files with the same path exist in multiple packages.  This is a very
common case in just about all packaging systems; most likely pacman
has some code in it to deal with this case too.

The code should combine certain types of configuration files,
directories with the same path, and so on.

What we would need to do is to modify this test so it can handle the
case of a directory and a symbolic link to a directory.  There's
unfortunately no simple, one line fix for this, but it could be fixed
with a larger patch.

I think this is going to be the best way to fix this.  If ntfs-3g
isn't using the empty directory for anything, it doesn't seem to make
much sense having it in the package.
