There is an unofficial version of mkisofs that implements
--duplicates-once. The website of the person who patched it (Alex
Kopylov) is permanently down. That version is commonly used in order
to fit 5 "flavors" of Window$ XP on one CD by hard-linking multiple
directory entries to the same sector(s).
Anyways, I am building a hybrid CD and there is a chance that there
are duplicate files.
However, I don't know how to use the output of "find cd-root -type f
-or -type l | xargs sha1sum -b" to find duplicate files. Maybe someone
can donate a perl/python script to find duplicate files and list them?
