Comment 4 for bug 1772137

I believe that this change has broken cosmic cloud-images.
there is 'journalctl -o short-precise' output of a 20180530 image booted in kvm at
 http://paste.ubuntu.com/p/xhzxNc4QtR/

From that you will see:
  May 31 15:54:35.838996 ubuntu systemd[1]: sysinit.target: Found ordering cycle on cloud-init.service/start
  May 31 15:54:35.839017 ubuntu systemd[1]: sysinit.target: Found dependency on systemd-networkd-wait-online.service/start
  May 31 15:54:35.839042 ubuntu systemd[1]: sysinit.target: Found dependency on systemd-networkd.service/start
  May 31 15:54:35.839064 ubuntu systemd[1]: sysinit.target: Found dependency on networkd-dispatcher.service/start

The result is that cloud-init.service does not run as it needs to.
