     With this, Udev starts from scratch at every boot :-)


     Looks like a very nice approach, but it's too hidden: if you 
inherit a machine which is doing that, it can take you pretty long 
before you find out who the hell is deleting the udev rules. Maybe 
rewrite the files with only a comment like


# This file has been wiped out by /etc/rc.local because I don't want
udev to rename my devices.
