this seems to be good tip for all debian users and admins

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. If you want to install udev in debian http://www.debianhelp.co.uk/udevinstall.htm and if you want to rename your network interface card http://www.debianhelp.co.uk/udev.htm

This is really good one and this will help more people
