udev allows Linux users to have a dynamic /dev directory and it provides the ability to have persistent device names. It uses sysfs and /sbin/hotplug and runs entirely in userspace.
udev comes with a lot of documentation and full manpages included in the source tarball.
udev is included in almost every 2.6 kernel based Linux distribution that is shipping, so please use the packages provided by your distro instead of trying to install from the source tree. But if you insist, please read the README files in the source tarball for how to set it up initially.
