Madpenguin has read and reviews “The Debian System
Concepts and Techniques” in the article “The Beauty of The Debian System”.
You can read the review nicely online.
But if you want more than chapter 4 from the book, you'll have to buy it.
Martin wants you to not only understand the tide, but also dive into it, and so Chapter 2 gives a detailed overview into the relationship between the Debian constitution, the developers, the users, and the SPI (Software in the Public Interest), the funding organization which receives and holds money on behalf of Debian.
In conclusion, let me say that Martin's book is not an easy read, but then few things worth doing are easy to do. You will be challenged by Martin's book, unless you are a wizard like Martin. But after you have toiled through the intellectually taxing tasks of examining, weighing, lifting, turning and tweaking the multitudinous creatures that inhabit the Debian forest, you will come out with a far, far greater appreciation for the beauty of the Debian System.
