Subject: createiso: Create Joliet tree with xorriso


This structure is important for isoinfo -J, which is in turn called by
virt-install.

This can be tested by using a bootable ISO by modifying it with a dummy
additional file and preserving boot records:

    $ xorriso -indev netinst.iso -outdev test.iso -boot_image any replay -map setup.py setup.py -end
    ...
    $ isoinfo -J -i test.iso
    isoinfo: Unable to find Joliet SVD
    $ rm test.iso
    $ xorriso -indev netinst.iso -outdev test.iso -joliet on -boot_image any replay -map setup.py setup.py -end
    ...
    $ isoinfo -J -i test.iso
    $
