I run a Debian system, and this book has excellent Debian-specific information. I learned a lot about the APT system and the structure of Debian packages. It seems to be geared towards those who would be interested in becoming a Debian maintainer, which may be me in the future but not right now. So some of the information was unnecessary for me, but still interesting. Well-written with good explanations of why things work the way they do in Debian Linux.

An excellent introduction to the details of your favorite linux distribution.
The edition I have still contains numerous typos but the author is very responsive and open for comments, purely in the opensource spirit :-)
So next editions can only become better!
