Query: Good book - Lousy support

The book was very informative. However after finishing it, I was stupified to discover that there is no online errata and/or script download site. (Or if there is one, it is sure hard to find). It seems that Wiley and "RedHat Press" are hopelessly behind the times. This is a serious flaw in an otherwise very useful book.
