udev is a program which takes information from the hotplug system and
creates (or destroys) device files in the /dev/ directory as they are
needed (as devices are added to, or removed from, the system). There
is a very clear short paper about it here, written by the principal developer::
http://www.kroah.com/linux/talks/ols_2003_udev_paper/Reprint-Kroah-Hartman-OLS2003.pdf
If you have a directory /etc/udev, then you are using it. Its great
advantage is that you can assign persistent device-names to devices
that are standardly added to and removed from the system (USB pendrives,
digital cameras, USB audio devices and the like).

Most sensible.
