I always wonder about how to fiddle hal rules. I have found hal rules
in the past I wanted to change (like putting different permissions
on the device file it creates), but I know if I change the actual
rule file, then the next time there is a hal update that file
will get updated and my changes will disappear.

Is there some magic way to properly define hal rules that override
existing rules in the installed system files?

I usually wind up huddled in a corner in tears when I try to understand
this stuff :-).
