Somehow you have to tell dhcpd which interfaces to listen on.  It's best if
the interface names are on the command line meaning they must be set in the
system start script somehow. On my system the variable DEVICES seems to be the
one but I'm not sure how that is set (my dhcp server isn't on Devil).

The manual says:  The names of the network interfaces on which dhcpd should
listen for broadcasts may be specified on the command line.  This should be
done  on  systems  where dhcpd  is  unable  to  identify non-broadcast
interfaces, but should not be required on other systems.  If no interface
names are specified on the command line dhcpd will identify all network
interfaces which are up, eliminating non-broadcast interfaces if possible, and
listen for DHCP broadcasts on each interface.
