А почему именно Joilet или RockRidge? Это общее свойство iso9660 и
умение mkisofs находить жесткие ссылки:

$ md test-iso
$ dd if=/dev/zero of=test-iso/f1 bs=100M count=1
1+0 входных записей
1+0 выходных записей
$ ln test-iso/f1 test-iso/f2
$ ln test-iso/f1 test-iso/f3
$ ln test-iso/f1 test-iso/f4
$ ln test-iso/f1 test-iso/f5
$ ls -l test-iso

  -cache-inodes
        Cache  inode and device numbers to find hard links to files.  If
        mkisofs finds a hard link (a file with multiple names), then the
        file  will  only appear once on the CD. This helps to save space
        on the CD.  The option -cache-inodes is  default  on  UNIX  like
        operating  systems.   Be  careful  when  using  this option on a
        filesystem without unique inode numbers  as  it  may  result  in
        files containing the wrong content on CD.
