I know this is getting a little off subject here, but what is the
_correct_ thing to do when cp gets a device file for its source? Should
it copy the dev file? I would think this would be the proper thing to
do. What I'm getting at here is this- should we taint busybox with fixes
for broken thinking? Isn't this what makes glibc and all of the standard
tools so big?
