Restarting Linux?

On another note, even CPUs/boards are hot swappable on some systems. I have pulled CPU boards out of sun servers (they are hot plug drawers) and replaced CPUs and memory on the fly.

If you can put your CPU into a park state and restart it from a park state then it would be technically possible to hot swap a single processor system.

Of course. If you pull your only processor you are pretty much done processing. In fact On most Sun hardware they use at least 2 CPUs per CPU board. If you only had one CPU board you couldn't hot swap it. You have to have more than one board. The last one I did had 5 boards (10 CPUs).
