Query: Not Quite There.

I bought this book for reference material. When I got the book the first thing I looked up was disk quota's. I went to the index and I found one key for disk quota's. (Pg 430-432). So I turned to it and I began to read. I was shocked to see what was written. It says "A stock Red Hat Linux system lacks true disk quotas," This was a surprise because I am using quota's on my Red Hat system. I have used them for a long time. I don't remember if I had to load an rpm or not, but even if I did the the book should point that out and tell you how to install and set up quota's. Instead the book gives you a script that will email your users if they use more than a pre determined amount of disk space. While nice it does not stop runaway processes or users from eating up the disk. Red Hat does have quota's and they are easy to use and maintain. I don't like books that don't get basic information correct. How can I trust this book for anything else?....
