Sorry for the late reply on this, yet, they are hardlinked.
Well, iso9660 is pretty simple. File data is basically referenced as
"offset,length". So hardlinked files can be trivially be made
referencing the same data blocks. There isn't something like a link
count field in the directory listing, so this is *not* visible with
"ls". The only way to figure the link count is scanning the whole file
system and see whenever there are other files with the same offset, and
as far I know nobody goes that extra mile just to figure the link count
for "ls".
take care,
Gerd
