So, it is my understanding that containers as deployed with kubernetes
generally don't boot up with systemd as PID 1 inside them, no?

If that's the case things should just work: if a container manager
copies in their /etc/resolv.conf, and resolved is not running in the
container, then nss-dns with traditional configuration is in effect as
before.

If otoh containers are now started with systemd as PID 1 inside them,
then this would also mean resolved is started inside, and yes in that
case the single-label thing and the DNS-server-order thing might
conflict with kubernetes' expectations. In that case it should be
sufficient to "systemctl disable" systemd-resolved however, and
nss-dns will take front seat again.
