Line 1: + + + + − At first let's dump/restore a trivial process without external dependences.
Intro
This HOWTO describes how to dump a very simple shell scripts that just loops and shows that it's alive.
First of all, if you try to simply launch such program and dump it crtools will fail. This is because the program you launch from shell shared session and terminal with the shell itself, but crtools should make sure, that no resources are used by external processes. So this simple test would be a little bit trickier, that just it.
