: Seriously: neat idea, but a little bit impractical. The amount of state : information in a running Linux system with lots'a'hardware and some 40Mb of : virtual memory in use (quite common if running X) is just too much. : : (I like the idea, however :-))
The Tadpole Sparc notebooks would dump all of the state machine to either a special file or swap (can't recall which) and then just load that machine image. It would, I believe, tell each device to shutdown. On reload it would reinialize everything. I'm pretty sure it flushed all its buffers before trying this so the state wasn't totally chaotic. Open files were still open, however, and programs still running were still running. This was done on SunOS 4.1.x and I think Solaris later.
