Query: I don't advise buying this book.

I bought this book with no knowledge of Linux, and I assumed it would be a good introductory reference to the subject. Unfortunately the included software is outdated, incomplete and it took me about two days to work out how to install it. The instructions given in the book seem to bear little relationship to the product on the CD. In short, don't bother with this book, look elsewhere for a beginer's guide.
