Syntax check?

[Jason Gerfen]

I am writing a web interface to help manage the ISC DHCPD service and 
need some clarification regarding DNS Zone updates, as well as utilizing 
the DNSSEC Zone update functionality. I am including a copy of the 
dhcpd.conf that the application is outputting and need clarification on 
if the functionality vs. my implementation of this functionality is 
correct. Thanks.

the public/private keys used during the update?
}
