Below is my FreeBSD 7.0 kernel configuration file. I created it on my reference system, to be used on four production servers whose hardware configurations differ some. For that reason there’re few options (indicated as “[OPTION]“) that are conditional for the configurations. I’ve also left in IPv6 options which are currently commented out, but that I may take into use later if/when IPv6 becomes more prevalent in the environment these servers operate.
