A LONG time ago an older (at the time, I think I've caught up) sysadmin 
told me to use "dig" to update the named.ca file.  Periodically he would 
run dig with no arguments and compare the output to the existing 
/var/named/named.ca file and copy it over the old one if anything had 
changed.

Maybe it's a bad habit, but I still do it.  I haven't had any adverse 
issues with it for about 15 years now.  Your mileage may vary!
