Udev rules - wyrfel

This creates the usual /dev/floppy, /dev/cdrom, /dev/mouse etc. symlinks. Additionally it also creates a dir /dev/names.d which includes symlinks which consist of more expressive names, which you can then use in scripts to provide nice names. For instance /dev/names.d/DVD-CDRW will point to /dev/names.d/sr0, when the Toshiba SD-R9012 drive is inserted into the Ultrabay. So you can make a script realise that the human readable descriptor of /dev/names.d/sr0 is DVD-CDRW.

Save this as i.e. /etc/udev/rules.d/00-t41p.rules to make it take affect.
