fakeroot(1) can do this, I think. LD_PRELOAD is one of the available strategies. As used by Debian to build packages, it basically says: Anytime you try to do something that's not allowed, I'll claim that I did it, and remember (inside myself) what was done, so if you e.g. install a file then read it, I'll act like it worked. But outside me, nothing has actually changed. It can persist its sate between runs.
