Amazon.com just posted my four star review of Mastering FreeBSD and OpenBSD Security by Yanek Korff, Paco Hope, and Bruce Potter. The book is chock full of absolutely sound administration advice from three experts with plenty of operational experience. However, I believe a second edition of this book should be radically altered to better deliver value to the reader. I hope they will consider incorporating my ideas when O’Reilly asks for a second version of the book. If you think they are helpful, please vote them so.”]
