Acknowledgments
I would like to thank all those at McGraw-Hill/Osborne, who made this book a reality: Tracy Dunkelberger,
Editorial Director, for her continued encouragement and analysis as well as management of such a complex
project; Dean Henrichsmeyer and Ibrahim Haddad, technical editor and technical reviewer, whose analysis
and suggestions proved very insightful and helpful; Jessica Wilson, acquisitions coordinator, who provided
needed resources and helpful advice; Bob Campbell, copy editor, for excellent editing as well as his
insightful comments; and project editor Carolyn Welch, who incorporated the many features found in this

initiated the project.
Special thanks to Linus Torvalds, the creator of Linux, and to those who continue to develop Linux as an
open, professional, and effective operating system accessible to anyone. Thanks also to the academic
community, without whose special dedication Unix would not be the flexible and versatile operating system it
is today. I would also like to thank professors and students at the University of California, Berkeley, for their
experience and support in developing new and different ways of understanding operating system
