I'm talking about a local caching resolver, not a server running somewhere else on the network. dnsmasq doesn't ship with a DHCP client

I don't get your point. DNSMasq doesn't ship with a client, because it's a server. It's a cacheing resolver and a DHCP server that is usually run locally. I don't know of any system that doesn't come with its own built-in (or standard) DHCP client.

Can you clarify your objection to DNSMasq?

His objection is that it doesn't replace the use case that resolvd is supposed to solve. Which is to provide a local service that can redirect DNS queries dynamically as local interfaces go up and down, which is where the integration with a DHCP client comes in.

Oh, OK. Thanks.

Makes sense; a lot of the systemd ecosphere seems to be about hotdesking, plugging things in and unplugging them, moving from one wifi AP to another, hibernating and so on. I don't encounter these use-cases, on the whole, which is probably a large part of why I find systemd so annoying.

Yeah, and I have some sympathies with what systemd is trying to do here, but the implementation is often backwards and/or half-arsed.

Still no DHCPRELEASE.

Dnsmasq and resolvd is a beast to tame in homelab, and split network.
