I would like to thank my family and especially my wonderful wife Beatrice
and little son Jonah for their patience and understanding during all the long
working hours while writing this book. Also I would like to thank the folks
at Packt Publishing for all their support and the opportunity to to write this
book, it was a great pleasure for me. Last but not least I would like to thank
Jonathan Hobson for writing the rst edition of this book: without him no
second edition of this book would have been possible.
I would also like to thank all of the mentors that I've had over the years,
especially Prof. Dr. Tobias Dykerhoff, who introduced me to the whole world
of Linux a long time ago and infected me with his enthusiasm about open
source and the free software movement.
