It's worth bearing in mind however that in the long run and if eudev is
still around then I would expect (2) to be by far the best option for
their reduced dependencies, older kernel support and just general
all round sane and considerate decision making.

It's been a few weeks since I checked, is eudev considered stable yet.
When it is I'd say (2) definately.

Why not both. I don't believe there is too much difference? and eudev
is tracking udev but less so the other way around I believe.
