Our experience was that the symlinks were not removed.
But that's an aside. My point is that the information *is* kept in two
places. It's kept in the driver, and its *also kept in the
scripts*. Think about it: the scripts have to know the names of
devices in /devices. Why bother? Just populate /dev directly.
