If you compare only the filename you'll probably link different file. To
do this you need at least to compare also the size.
But even if you take into account the size nothing warranty file are
really the same. Think to md5sum files, an md5 has fixed size and
filename will probably also have same lenght.

I did a script to do this, this script check the md5 of
files before linking them to avoid mistake.

BTW: I am not sure rsync fix hard link afterward.
