Udev Rules
Udev is the Linux subsystem that supplies your computer with device events.
I interacted with this because I had to configure the Udev rules for the realsense in order for it to work properly for NVIDIA: https://nvidia-isaac-ros.github.io/getting_started/hardware_setup/sensors/realsense_setup.html
It detects when you have devices (mouse, keyboard, joystick, network card, etc.) plugged into your computer.
That makes it a potentially useful utility, and it’s well-enough exposed that a standard user can manually script it to do things like performing certain tasks when a certain hard drive is plugged in.

Restarting the Udev rules
sudo udevadm control --reload-rules
sudo udevadm trigger
