Note that it isn't critical that your root hints file be totally up to 
date.  One of the first things that named does when it starts is query 
one of the root servers to get the current set of NS records, and then 
it uses that.  The root hints file is just used to find a root server to 
send this query to, and perhaps to perform other recursions while it's 
waiting for the answer.  So unless your root hints are totally whacked, 
you're fine.
