I was motivated to read this from all of the good reviews here. After completing the exercises, I sadly cannot recommend this as pedagogical material. At the end, I did have a working linux installation "from scratch", but I have no idea how or why it works. This books provides several instructions (90% of which are "make && make install"), but no explanation or motivation behind them, often urging the reader to simply refer to man pages. After building my own LFS, I'm unfortunately none the wiser about Linux or its internals.
