I have a similar interest: I want to be able to take a process, save its state to a file, reboot, and reload the process. Possibly on a different machine. I hope you realize that there are _lots_ of points of failure, things like file deletion. You should look at the mosix clustering project; they save the userspace state of a process, and transfer that across the network, and have system calls run on the remote host, which has all the arch-specific stuff. A process ("task") is defined by a task_struct, in include/linux/sched.h., but that definition is not at all self-contained. See [http://www.clarkson.edu/~pryzbyj/task/struct-task_struct.html] for some work I did to convince myself of this. (I've given up on that document). In short, there's no good way of doing this .. mosix saves the user context easily enough, but, sadly, saving the kernel stuff is, at best, extremely tedious. Let me know if you come up with anything else.
