For the record, I'm not opposed to this but given how late things have
gotten in the cycle it seems rather ambitious.  I definitely agree
it's not something we would want to diverge with Debian on.

In particular, I'm concerned about the number of packages which would
need to be updated for this change, since we could easily miss something
or introduce a typo, and time is short to get sufficient testing,
triaging, and patching done prior to release.

Also, while configuration fixes can be easy to apply, review, and sru,
certain kinds of configuration changes can cause problems during
installation, so if we don't get all such issues fixed before the CD's
are cut, it could make for a lot of buggy installation experiences.
I do not know how large to quantify this risk though.  Perhaps its

On the other hand, I do agree that the udev approach for configuration
is funky.  The syntax style of the configuration files is quite a bit
different than people are used to and will be irritating for people who
have to maintain both LTS systems and Lucid+N systems.  From our end,
there will be some differences in maintaining things, but I'm less
concerned here: I think it'll play out that for the next 3-4 months
we'll be doing fixes for Lucid, then after that will focus on Lucid+1
and the amount of udev-rules patching we do will probably drop off quite
a bit.  I expect a lot of the LTS X maintenance work will be done by the
new hardware enablement X person, so as long as they understand how to
do udev and xorg.conf.d rules, we should be ok on our end.
