Comment 9 for bug 1432829

-- adt --
  Note, my adt runs so far have failed each time (and after 30+ minutes)
  The last last failure due to guest running out of space, so changed to 20G
  (default 4)

- boot system with 'iface eth0 inet dchp' in ENI + auto + unplugged-network
  - [P] service should fail, boot should be slow
        uptime on login was in the ~300 second realm (359.19 recorded)
  - [P] network-manager should not bring up network

  Note: i did have a default bad route after bringing up network manager connection to wifi.
  I do not believe this was related to systemd changes but more likely a result of lxc
  or some other software trying to bring up a default route (lxc is installed and lxcbr0 up).
