If one's not doing DDNS updates (updating a DNS server with DHCP
configured records), which sounds like it, then it's probably better to
directly specify so, than have a half-configured server.
i.e. ddns-update-style none;

Hmm, I'd have thought that'd only be needed if you had more than one
DHCP server on a network (a bad idea unless they're deliberated
configured to be co-operative), or if you used a PC on different
networks, but it may well be required.
Taken from the dhcpd.conf man file:
"Network administrators setting up authoritative DHCP servers for
their networks should always write authoritative; at the top of
their configuration file to indicate that the DHCP server should
send DHCPNAK messages to misconfigured clients. If this is not
done, clients will be unable to get a correct IP address after
changing subnets until their old lease has expired, which could take
quite a long time."
