"Re-port" may be a bit strong. Internet stuff from Berkeley was folded into the research code (for a huge increase in kernel size). But I think it was done by pasting Berkeley code into local source, rather than the other way around. But, since much of the rest of the BSD kernel was Bell Labs code, it's probably right that the result of the merge had more code in common with BSD than with Research. If you ask, though, what fraction of Research code survived the merge, it was probably larger than the surviving fraction of the total BSD code. Doug
