Comment 1 for bug 188341

I see no sense in this kind of usage....

But please note: genisoimage is a fork from a 3 year old mkisofs version it still has bugs that have
been fixed long ago in the official software....

If you _really_ believe that this usage makes sense, just call:

mkisofs -f -R -print-size -find .

Note that you need a recent mkisofs e.g. from ftp://ftp.berlios.de/pub/cdrecord/alpha/

The built in libfind correctly handles loops created wirth hard linked directories
which is what you did emulate in your case.
