Are your sure "append" works like this on the server? I only know that
option from the client configuration. I cannot see it mentioned in the
man pages for dhcpd 4.3.6b1.

We use syntax like this:

   option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list, 43);

You shouldn't have to modify the "dhcp-parameter-request-list" though.
The client should request it normally by itself. But there are of
course clients that misbehave.
