Hello syslinux, Merry Christmas! These patches will make extlinux work with umounted ext2/3/4 filesystem, for example: $ extlinux -i /dev/sdXN or $ extlinux -i file_block Also it can work with something like: $ extlinux /dev/sdXN --reset-adv or $ extlinux file_block --reset-adv We don't use a new option (I planed to use "-d" but it is already in use), it will check whether the
