<xnox> smoser, yeah, so like cloud-init.service should want/after systemd-resolved.service; or e.g. systemd-resolved.service should declare itself before cloud-init.service
<xnox> smoser, i think changing it in systemd unit might be better.

Bug description:
  I use no-cloud to test the kernel in CI (I am maintainer of the bcache
  subsystem), and have been running it successfully under 16.04 cloud
  images from qemu, using a qemu command that includes:

  -smbios "type=1,serial=ds=nocloud-
  net;s=https://raw.githubusercontent.com/mlyle/mlyle/master/cloud-
  metadata/linuxtst/"

  As documented here:

  http://cloudinit.readthedocs.io/en/latest/topics/datasources/nocloud.html

  Under the new 17.10 cloud images, this doesn't work: the network comes
  up, but name resolution doesn't work-- /etc/resolv.conf is a symlink
  to a nonexistent file at this point of the boot and systemd-resolved
  is not running.  When I manually hack /etc/resolv.conf in the cloud
  image to point to 4.2.2.1 it works fine.

  I don't know if nameservice not working is by design, but it seems
  like it should work.  The documentation states:

  "With ds=nocloud-net, the seedfrom value must start with http://,
  https:// or ftp://";

  And https is not going to work for a raw IP address.
