Acknowledgments
Since I was hired by Red Hat, Inc. over three years ago, I have been exposed to the best Linux developers, testers, support professionals, and instructors in the world. I can't thank everyone individually, so instead I salute the culture of cooperation and excellence that serves to improve my own Linux skills every day. I don't speak well of Red Hat because I work there; I work there because Red Hat has earned its reputation as the leading force in Linux development.
