Returning to restaurant: you just went off a problem. In your case restaurant is persistent. And a road to your home exists. Suppose, home exists too and you do not rebuild it returning from the dinner.
And at the moment when Linux boots, all the world is absent and is built again from files.
(There's not just no spoon - there's no restaurant. :) And no white rabbit. :)
My home is persistent, and this means I have to clean it up and repair it. I would like to have a magic "reboot" button, which restores my home to blueprints and discards everything not stored in cabinets, drawers and containers.
Ants infestation? "reboot". Walls need painting? "reboot" Don't want to wash the dishes? "reboot"
Isn't this cool? And the best part, we have this for PC already -- and we use it a lot. I can see why one would want to have a small part of the system persistent, but the the entire system? This does not seem useful.
