I would like to thank my wonderful wife, Kathy, for all she does to make sure I have the time to do things like review this book and travel to give presentations on SELinux. She is the joy of my life and has helped me become the man I am today. I'd also like to thank all my children past and present: Zoe Jane and Caroline, who remind us to love and cherish the time we have as a family.
