I wish RH would maintain a little "new technologies" page on their site, this 
HAL, udev, mdnsresponder etc have been showing up in FC3 and I don't have any 
idea what they are.  The Jargon Buster on the Fedora page doesn't know what 
they are either.  If it already exists somewhere please reply pointing to 
it :-)

Anyway, my little store of knowledge on the subject of /dev (not udev) says 
that you can make device "files" anywhere, not just in /dev, and that you can 
have multiple device files for the same device no problem.  The major and 
minor numbers you give mknod make the file "special" and associated with a 
particular kernel device driver on the kernel side, not that it is in /dev.  
Whether this is useful to unpicking the mysteries I am not sure.
