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'
