[PATCH] udev - man page update
Hey it's not longer the "goal" to provide a dynamic dev directory, we have just arrived. So I change it to more self-confident words :) I've also added the completly missing environment variables to the man pages. To stop the misuse of the PROGRAM= call paramenters, we better mention its limitations.
