There is no such option. Could you explain your desire? 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? -- Andrey Vul

Mkisofs checks for pysically and virtually (e.g. via -graft-points) hard linked files. Files with the same inode number appear only once in the .iso image created by mkisofs. The patch with -duplicates-once is from before December 2001 in a time where POSIX did not allow 64 bit inode numbers. At that time, Cygwin did not work properly as it hashed 64 bit NTFS inode numbers to 32 bit numbers. Since a long time, Cygwin just uses 64 bit inode numbers for NTFS and mkisofs has no problem to detect hard lionked files.

The problem is that the one that exists right now, the patch (against the official sources) cannot be found because the original site (bootcd.ru) is permanently down. Or do I need to make a table of SHA-1s to weed out the identical files? I found this link: http://www.911cd.net/forums/lofiversion/index.php/t15282-350.html I'm not sure it will help but may be worth a look. Dale :-) :-)
