Why do you include different contents to main dhcpd.conf?

Just put all identical configuration to single included file
and include it to two distinct dhcpd.conf's each having own "failover peer"
statements and, perhaps, something other like "subnet".

And make your DHCP servers use such distinct dhcpd.conf's
Nothing makes you always use "dhcpd.conf", you may use any name
and just run the daemon with corresponding "-cf config-file" flag.
