udev is used in the "embedded" world all the time, there's no reason you
can't just take the shipping tarball and use it in your product just
But discussion about any problems you have with that, would not be
answered by the document described originally, you can just ask them on
the linux-hotplug at vger.kernel.org list.

Use the provided tools and don't roll your own. It will save you time
and frustration. Look at all of the mess that people have gone through
to try to re-do udev on their own already and the problems they had with
it (google in android, busybox version of udev, etc.)
