[CentOS] New Bind Update

I was wondering if the new bind update is going smoothly for those who 
have done it?

I've been a little hesitant to run it yet as the last time forced a bit 
of time fixing things. I'm trying to plan if I need to have some hours 
available for this or if it is like most of the time.. just do it and 
everything's ok.

Best,
John Hinton
