I just added that Friday. We've been getting the original error message
for weeks? months? for the configuration *without*
   option dhcp.bootfile-name

For example,
Apr  2 13:45:44 <hostname> dhcpd: parse_option_buffer: malformed option
dhcp.bootfile-name (code 67): option length exceeds option buffer length.

which is the annoyance I was trying to fix. At that time, the dhcpd.conf
section for pxebooting was
group {
        allow booting;
        allow bootp;
        filename "pxelinux.0";
        option subnet-mask 255.255.254.0;
        option routers  <subnet IP elided>;
        default-lease-time 172800; # 2 days.
        max-lease-time 432000; # 5 days.
