I will add my $0.02. The named executable has the root information built
in so that it can start up if there is no named.root file available.
So, if you had no named.root file but did have the latest release of
Bind then you would have the current data. If you do not update Bind
the moment that a new version is released then you need a current
named.root file. Just go get a new one from the server listed at the
top of the old file.
