There''s already such a file present.  Are you suggesting I just  
concatenate the content of the permissions file onto that?

Perhaps this is a Gentooism? I'll look on their site and see if  
similar strangeness is reported.

The rule on this Gentoo machine is:

BUS=="ide",	KERNEL=="hd[a-z]",	ACTION=="add",	IMPORT="/sbin/cdrom_id  
--export $tempnode"

Of course I just re-booted three times and it came up"right" each  
time (hdc=DVD,hdd=DVD1).

Maybe I should go to Vegas?

I think I'll do nothing 'till it happens to get reversed again, then  
see if it is the hdc/hdd or just the dvd/dvd1 that get reversed.

Thanks for the input.
