Current udev _cannot_ be used to
populate /dev, it doesn't contain any mknod() calls enymore.
Actually mknod isn't necessary since device files are created by
the kernel in /sys/block/dev and /sys/char/dev and the hotplugger
only needs to copy them to /dev.
Erratum. mknod is necessary because the files in
/sys/devices/char/dev and /sys/devices/block/dev appear as text files
containing the major and minor numbers separated by a colon.
Erratum again. The devices are accessible through symlinks in
/sys/dev/char and /sys/dev/block. The name of each symlink apparently
duplicates the contents of the dev file in the directory it points to. Eg:
/sys/dev/char/4:0 --> /sys/devices/virtual/tty/tty0/
and /sys/devices/virtual/tty/tty0/dev contains "4:0", meaning the
device file should be created with
'mknod /dev/tty0 c 4 0'
