I just checked with ls -i, and the inodes are not the same for the file in
binary-i386 and its msdos file. This probably explains why none of the
utilities recognize them as hard links. (they were definitly hard links on
the archive that I built the CD from) It seems that ISO9660 deals with
this differntly, unless it is a bug in mkisofs?
