It is disputed, whether the specs say that the partitions must be marked by 0xEF in legacy MBR tables and by C12A7328-F81F-11D2-BA4B-00A0C93EC93B in GPT. In practice there seems to be no such demand. A zillion Microsoft users would complain if the specs were interpreted narrowly. > A USB drive may be formatted without partition table. The specs only talk of partitions. Whether the real implementations would look into the FAT filesystem of an unpartitioned device would have to be tested. (Boot firmware is a bitch. The hunchbacked partition layout of Debian ISOs is still the one which boots on most machines. Other distros decided to clean up at the cost of losing some old laptops.) > 7z and bsdtar can extract content of ISO files without mounting images. But mounting needs no special software and gives you the opportunity to use many different ways of copying, which may be decisive when the target is a heavily restricted filesystem like FAT. (I still wonder which software in the Debian ISO needs the symbolic link "/debian -> ." and which parts of the file tree are accessed via this link. Probably one can avoid to duplicate the whole tree under /debian.) Have a nice day :) Thomas
