Comment 4 for bug 1295229

The 17.10 install was default, with:

hosts: files mdns4_minimal [NOTFOUND=return] dns

The user gave up and re-installed with 16.04 so we don't have access any more to diagnostic output.

However, the issue here was that the lookup should have been satisfied by 'files' since the system hostname was in /etc/hosts, both for IPv4 and IPv6.

Regardless of that, what nacc and myself found perplexing is the [NOTFOUND=return] - if mdns fails to resolve the name surely NSS should 'continue' and try to resolve using DNS, not return?
