7.2 A word of warning
Before starting it is only proper to state the obvious. You should
never trust anyone's advice about configuration or security without
running it past your own grey matter first. The examples provided here
are just that: examples. They might apply to you as written and they
might need to be modified. You should never accept and use an example
without thinking carefully and critically first!
Also, in any book of recipies or guide to successful living you
know that there are simplified answers to complex questions and
you should treat them as such. There is no substitute for real
understanding.
