Of course but this argument is confusing - we are talking about DHCP
client, not server.

I'm using the pfSense default DHCP server for both IPV4 and IPV4 - as far
as I remember, this is isc-dhcpd and in a previous iteration of my home
infra, I had isc-dhcpd working (with dynamic DNS) for both v4 and v6.

I'm saying that the base system's choice of DHCP client has little bearing
on pfSense or OPNsense. I don't understand the comment on 'former status'.

Of course, whatever solution we choose for DHCP needs to be integrated
properly. To be honest, all I want is a DHCPv6 client integrated in base -
I don't care if it's dhcpcd or something else but until we have that, IPv6
is a second class citizen (IMO).
