Good point. I think “none" is better than "just Linux", which would force the authors to describe each option in a TCP and protocol standards way (and not implementation specific). Sounds like a lot of work though.

That much said, that might turn it into a difficult document to read. In the end, what many people need is a single sysctl.conf (etc.) file to deploy. :-).

Cheers,
