[CentOS] Bind - built in root hints?

Over on the bind-users at lists.isc.org list, I am in a discussion about 
building the named.zone file, as Centos 6.3 does not provide it.  It 
DOES provide a named.ca which is already old (wrt AAAA records) compared 
to the named.zone provided by internic.

A few contributors have stated that now the hints are built into bind 
and you can see this with:

strings /usr/local/sbin/named | grep A.ROOT-SERVERS.NET

Well it looks like Centos has it at /usr/sbin/named and there are no 
such strings in there.  Oh, these hints come from "lib/dns/rootns.c in 
the source code tree".

So are the hints built in here?
