And Linux does. alt-sysrq-k kills any programms running on the terminal allowing the system to start up a fresh known-good login prompt for you. > that this was a risk, and repurposed control-alt-delete to fulfill the > task of bringing forth a known-good component of the operating system. I have always thought ctrl-alt-del was a bad choice. That is traditionally used for rebooting the system. You don't want users hitting that key sequence on every computer they walk up to because occasionally they will cause systems to reboot. > So, other than power-cycling my machine, I ought to have a way that > I can bring up a known-good login prompt (console or XDM) that no > user-space code can intercept.
