Move DHCP service to dns1.p.b
The DHCP server on the UniFi Security Gateway is pretty limited; it cannot manage static leases (reservations), and does not offer any way to build dynamic values for e.g. hostname or boot filename. Rather than give up these features, I decided to just move the DHCP server to one of the Raspberry Pis; the DNS server made the most sense. To facilitate this move, I created the *pyrocufflink-dhcp* host group, and moved the DHCP configuration variables there. Thus, it was a simple matter of adding *dns1.pyrocufflink.blue* to this group to relocate the service. Of course, to serve clients on the other subnets, the gateway needs to have DHCP relay enabled and pointing to the new server.
