Hmm, even if directories are not hardlinked to each other, the files they
contain could be. It seems my Debian/SPARC CD is burnt like that (all files
under disks-sparc/2.1.8.1-1999-03-01 & disks-sparc/current are sharing the same
iso9960 inode, so they don't occupy twice the required size).
# du -s /cdrom
596714 /cdrom
# df /cdrom
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/scd0 553552 553552 0 100% /cdrom
596714-553552 = 43162 = approx the size of disks-sparc/current (41713).
It was built using slink-cd and mkisofs with farm symlinks patch.

Not using symlinks, which are only visible if RockRidge is supported, would
ease a DOS user to get & write its boot disks from the CDROM floppy images.
