Hey Dan, My intent was not to task anyone or add to their burden. I apologize if that is how my questions were perceived upon receipt. My goal was to perhaps start a dialogue, brainstorming ways to improve processes along the way. As a downstream derivative of FreeBSD, one who will indeed be in the same place as FreeBSD with regards to security announcements, disclosures, timelines, etc, we at HardenedBSD would like to learn =66rom the experiences of others. The only way to learn from others is to collaborate with them--the true intent of my questions. However, if FreeBSD would not like help with regards to security, or would not like to impart of their wisdom to others, perhaps this would be a good place to end the discussion. Even if you mean well and have the best of intentions, they eat you alive.
