As taken from the Redhat website's copy of 7.2 documentation: 1. Near the bottom of the page under the header Lease Database, dhcp is left out of /var/lib/dhcp/dhcpd.leases in the third paragraph, second sentence, starting with "Use the command touch to..." 2. Despite the manual telling us to touch this file, it comes with the DHCP server RPM, making the above request more of a "If DHCP doesn't work, do this " than a "Do this before starting DHCP) thing. 3. Under Starting and Stopping the Server just below, the explanation on how to limit the server to only one network interface seems to be out of date, i.e. ignorant of the DHCPDARGS variable imported from the /etc/sysconfig/dhcpd file, making it unnecessary to mess with the init script. Also, if there's a way to edit that at a GUI level, please mention it there.
Thank you for bringing this to our attention. For the next release, I have made the corrections and added a list of options that can be specified in /etc/sysconfig/dhcpd.
