Just Reboot Now Dammit
Every person has vices and eccentricities.
One of my quirks is rebooting or powering down when using a Live ISO image. When I am finished using a Live ISO I want the system to respond immediately. Really. Dispense with the formal reboot and power down ritual. Just act now dammit.
A Linux kernel magic key sequence is faster than waiting for a Live ISO to reboot.
