In our environment, our dhcp client machines (rhel or centos) gets their
hostname by dns lookups (Not sure why).
Our dhcp server generally just provides the usual configurations like
dns/search optionse/etc. The ip addresses for our dhcp range have both
forward and reverse mappings on our dns server and the clients obtain
the proper fully qualified host name upon dhcp request.
