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
итого 512520

-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.
