Recent state of udev
This is Kay Sievers's web page, the maintainer of udev. I have to read it later carefully.
Since I am not so good at English, I need enough time to take a look at some documents....I really envy native English speakers, they can do it much more easily.

After reading it, it was not so long, don't hesitate to jump into documents. I'll keep it in mind from now on:)
