Additional information

Nothing seems unusual in journalctl, so we must be missing configs defined here.

added systemd type::bug labels

I cannot reproduce this in a new systemd chroot, but I wonder if it's related to this upstream change if you're using wireguard-tools: https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/80058

If so, systemd-resolved probably needs to have a lower provides_priority

That seems to be it. A quick MR will probably fix that.
