Says the LSB standard?

Nothing you can do in the sysfs tree will create a subdirectory in udev.
Leave it as a rule.

Patches gladly accepted :)

What does LSB say on this? It's been dri/cardX ever since dri was created, long
before I started working on it.

LSB says to follow what LANANA says, and the LANANA documentation says:
226 char Direct Rendering Infrastructure (DRI)
0 = /dev/dri/card0 First graphics card
1 = /dev/dri/card1 Second graphics card
...
So yup, you should be in your own subdirectory. Care to send me a patch
for udev.rules that adds this subdir for all dri devices?
thanks,

This is what I'm using to force the subdir, is this the best way? Should there
be a separate file for rules that are never to be changed?

It's a good start. Works for me :)

All rules can be changed, that's why udev has a rules file :)
I'll add a comment in the file about keeping LSB names for dri devices
with that rule...

Thanks, I've made this change to the file.
I think it's about time we start working on a "default" rule file that
works for everyone in a LSB system. And then provide an "example" file
to show some rules that might be useful to people.
thanks,
