 Even when you specify the interface list
 
 dhcpd=YES
                  dhcpd_flags="-q vlan7 vlan8 vlan9 vlan10 vlan11 vlan12"
 
 dhcpd will complain about what it perceives as an overlap (note vlan2 is 
 not listed above)::
 
 dhcpd: Multiple interfaces match the same subnet: vlan2 carp2
 dhcpd: Multiple interfaces match the same shared network: vlan2 carp2
 dhcpd: Multiple interfaces match the same subnet: vlan7 carp7
 dhcpd: Multiple interfaces match the same shared network: vlan7 carp7
 dhcpd: Multiple interfaces match the same subnet: vlan8 carp8
 dhcpd: Multiple interfaces match the same shared network: vlan8 carp8
 dhcpd: Multiple interfaces match the same subnet: vlan9 carp9
 dhcpd: Multiple interfaces match the same shared network: vlan9 carp9
 dhcpd: Multiple interfaces match the same subnet: vlan10 carp10
 dhcpd: Multiple interfaces match the same shared network: vlan10 carp10
 dhcpd: Multiple interfaces match the same subnet: vlan11 carp11
 dhcpd: Multiple interfaces match the same shared network: vlan11 carp11
 dhcpd: Multiple interfaces match the same subnet: vlan12 carp12
 dhcpd: Multiple interfaces match the same shared network: vlan12 carp12
 
 -- dhcpcd needs to learn carp interfaces are special.
