On 16.04, "/etc/resolv.conf" was a symlink to
"/run/resolvconf/resolv.conf" and the latter was generated from the
"dns-*" values in "/etc/network/interfaces".

On 17.04, "/etc/resolv.conf" is a symlink to
"/run/systemd/resolve/resolv.conf" and the latter is generated by a
systemd drop-in that only sets up a "nameverser ..." entry.
