> Without genisoimage -c 0,[NWA], the OS can not find the new superblock.
Of course, I meant: genisoimage -C 0,[NWA] (with uppercase "C"). Currently, this has to be done manually: genisoimage -C 0,[NWA] [other options] -o tmp.iso [files and folders to add] growisofs -use-the-force-luke=seek:[NWA] [other options] -Z /dev/sr0=tmp.iso NWA is always in 2K (2048 byte) logical blocks. The NWA can be found using dvd+rw-mediainfo /dev/sr0 (or whichever device name is in use).
