With one very large caveat.
Be aware that updating bind via yum can result in your existing bind
configuration files being renamed to something.rmpsave and your name
server left in a dysfunctional state. I suggest that you consider
excluding bind from normal updates and only update it when you are
ready and able to check for possible configuration issues.
