Comment 14 for bug 1626617

Verification done for yakkety:

Preparing to unpack .../nplan_0.23~16.10.1_amd64.deb ...
Unpacking nplan (0.23~16.10.1) over (0.12) ...
Setting up nplan (0.23~16.10.1) ...

Verified that nameservers can be set via netplan in yakkety-proposed; used the configuration below:

network:
  version: 2
  renderer: networkd
  ethernets:
    ens4:
      dhcp4: yes
      nameservers:
        search: [ 'cyphermox.net' ]
        addresses: [ 10.10.10.1 ]

The correct nameservers are used by systemd-resolved, but /etc/resolv.conf will not include the values directly (because it gets 127.0.0.53, as a side-effect of the use of systemd-resolved behind resolvconf.
