It should be fixed after reverting #4544

This still does not work. Looking at that patch looks like the exact behavior I am describing was added again, checking to be sure there is at least one tracked interface before adding the PD bits. I am not sure why that was not working before but the PD code was definitely not added to the conf file in that case.

This is what is currently installed as dhcp6c_wan.comf with a PD and one track interface set:

interface vtnet1 {
    send ia-na 0;    # request stateful address
    send ia-pd 0;    # request prefix delegation
    request domain-name-servers;
    request domain-name;
    script "/var/etc/dhcp6c_wan_script.sh"; # we'd like some nameservers please
};
id-assoc na 0 { };
id-assoc pd 0 {
    prefix ::/56 infinity;
    prefix-interface vtnet0 {
        sla-id 0;
        sla-len 8;
    };
};

With the PD configured on WAN and no interfaces set to track I think we need something like:

interface vtnet1 {
    send ia-na 0;    # request stateful address
    send ia-pd 0;    # request prefix delegation
    request domain-name-servers;
    request domain-name;
    script "/var/etc/dhcp6c_wan_script.sh"; # we'd like some nameservers please
};
id-assoc na 0 { };
id-assoc pd 0 {
    prefix ::/56 infinity;
};

Resolved now.

Applied in changeset 13fde8fabb8e7ad6bc588b13504ad1068e4c45ba.

This seems to work great now. Thank you.
