Query: Not for the intermediate to advanced user

I bought this book to increase my FreeBSD knowledge and skills as this book is listed for intermediate to advanced level users. That is not the case. The book focuses only on the specific preferences of it's authors, ignoring many important aspects of the OS. For a person new to UNIX who doesn't have a prefered shell, editor, X client, etc, this would be a decent book to begin with, however for those of us who have those preferences get ready to read about Authors' bias against them. Further, there are several places where information is not correct at all. The index is horrible, making FreeBSD Unleashed unusable even as a reference guide. Save your money, and buy a book written by someone who knows what they're doing.
