I am very confused about the way kernel mount a disk-based root like root=/dev/sda1. Does this special file "/dev/sda1" exist inside the very very first filesystem, rootfs? How does the kernel get the major, minor number out of this line "root=/dev/sda1"? Otherwise, there is no way to reference the actual device, right ? I have browsed the whole source tree and found no place where command_line (or cmdline) is parsed to convert "root=/dev/xxx" to something like kdev_t or dev_t. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
