Udev rules and the management of the plumbing layer

From the experience (admittedly very little) with writing rules for the Wacom tablet PC, I
prefer the Ubuntu rules. The Wacom digitizer found in tablet PCs has 2 sub-units, 1 for the
pen input and 1 for the touch screen. The standard rules choose the touch screen as
\dev\input\wacom, which is not really very helpful. I found that on Ubuntu enough information
is provided in the hierarchy of udev nodes to differentiate the 2 sub-units, but this is not
present in the standard set of rules (as seen in Gentoo). At the time I was very surprised
(and annoyed) that the rules weren't standard.

Unlike the other commenter I have a more thoughtful response to your experience.

I see this as exactly the reason why distributions should converge on udev rules. You are
seeing the consequences of divergence, you are expecting the same results on all
distributions, which is why the Ubuntu rules should be sent upstream so that all may benefit
from them.

That Ubuntu has not done so, or upstream has decided not to merge them, is concerning.

While I did know that, I found it out of place, so I found it more productive to give a good
answer instead of making jokes.

I do not mind jokes, but I just felt his post deserved a better reply than yours.
