What creates those "conservative defaults" before device drivers are
loaded? What happens if a device driver is loaded (i.e. built-in)
before the administrator changes the permissions?
Also, you you have to write the entire permissions database again?
Finally, you can get a more traditional effect by doing:
# ls -l /dev
# chown root.lp /dev/lp*
