So getent works with the libnss_resolve module but not with the
libnss_dns module.

So "host" fails with both "resolve" and "dns" (previously it was
failing with "resolve" and returning).

I don't think that any more tests are needed.

The problem seems to be that host and dig can only resolve short
("zero-dotted? LOL) hostnames if there's a domain or search entry in
"/etc/resolv.conf"; and it might or might not be related to the fact
that LLMNR cannot be turned off
