Another tutorial on these hairy udev rules! Getting the base concepts about udev rules
Udev is really cryptic and advanced. It is often hard to trobuleshoot if you need to. What is it? Udev is the device manager for the Linux kernel. Udev dynamically creates or removes device node files at boot time in the /dev directory for all types of devices. Udev is now part of systemd as you can see by viewing the “udev” file names included with the systemd RPM package.
