[CentOS] Another Fedora decision

While this discussion has been very interesting, I would like to
encourage participants to be very careful about disclosing the
specifics their own security efforts.  While is good to discuss the
pros and cons of strategies, disclosing the details of the exact
strategies that you use, no matter how good they are, is a bad idea.
This is typically hard information for an attacker to acquire and they
would run the risk of generating too much noise if they were to try to
acquire it.  A somewhat subtle trap is to disclose information about
time, e.g., when you last changed a password on a system.
