For some years, I've wanted to create a free implementation of System V, and then move on from there. (I know there's limited utility for such a thing, because of the BSDs.) A few things actually hinge on this. If it were considered a fact, and not a mere opinion, that 32V was PD, then I could be sure that certain things were safe to use, rather than having to rewrite (including some particularly tricky stuff the BSDs never fully reimplemented, like diff(1)). I actually did write a replacement for the Caldera header. (I still hold that the Caldera license is void because it has a Caldera copyright claim, and it has been proven in court that they didn't have the copyright to give.) It just says why I think it *should* be safe to use the code. -uso.
