Err, no.
The root zone changes twice a day and its contents change quite =
frequently as TLD managers update their name servers, do key rollovers, =
etc.
If you're going to copy the root zone, I'd recommend using a zone =
transfer from the name servers described in =
http://dns.icann.org/services/axfr/ or, at the very least, set up a cron =
job to pull the root zone twice a day.
WRT the root _hints_ change, setting up a cron job to pull, verify, and =
install the root hints file periodically (once a month should probably =
be sufficient) would probably be a good idea.
