Although: now that I look at the ISO structure with isoinfo, it does
appear that the files are not actually duplicated - they are pointing to
the same sectors. Reading the genisoimage man page, it does recognize
hard links and make only one copy on the resulting ISO image. Should
have done more research on that part first - d'oh!
That's curious, when I mount the server dvd ISO, those files have
different inode numbers.
I can't tell from the isoinfo man page what the numbers in brackets mean.

And it looks like FIEMAP doesn't work on ISO 9660. I get nothing
useful from filefrag -v.
