If you read the recentish series of Gearhead columns on Knoppix you will know what a wonderful operating system it is. It will come as no surprise to you then that books on Knoppix are now appearing ... Gearhead discussed "Knoppix Hacks" (O'Reilly) some time ago and now from not only the same stables but with the same jockey, Kyle Rankin, comes "Knoppix Pocket Reference."
Despite being a trim 75 pages of text this is a tremendously useful book if you're just getting to know Knoppix. It starts with a discussion of all of the "cheat codes" -- startup the command line arguments that can be used to configure various system attributes and then moves on tools, how to install on a hard drive, security, using Knoppix to repair Linux and Windows systems, remastering Knoppix and finally a discussion of UnionFS.
Recommendation: If you're looking for a nuts and bolts book on Knoppix that gets reasonably deep into the subject, this is it.
