This is the definitive Debian manual, and I wish it had been written years ago. Mr. Krafft's affection and enthusiasm for Debian is apparent, and makes this book a pleasurable read.
This is the only Linux book (probably the only COMPUTER book) that I have read cover to cover. I've considered writing a review for LQ, but there are plenty of reviews on the net already, and I couldn't be any more enthusiastic than everyone else who's gotten there ahead of me.
Only comment I'll make is, "Don't read it if you're not a Debian user; unless you're ready to change your primary distro anyway."
