My teachers in grade school hammered at least one lesson into me:
“If it is in a book, it must be true”
Since I was such a good student I remember this little aphorism exactly as it was stated even to this day. This is great news for Server Fault as it was mentioned in the 4th Edition of the Unix and Linux System Administration Handbook as one of the most significant resources of UNIX and Linux information on the web. I already felt this was the case myself, but it is good to know that it must be true.
