With rsync --link-dest, is it possible to determine which files are new?

Yes, if a file is a different inode it will be reported by my script
even if that is the only difference.  If the inode number is different
then the file is in fact different and takes up additional disk space.
If that is the only thing that is different you might be using rsync
incorrectly.  This is also why I use md5sum to check files that have
different inode numbers but the same mtime and file size.
