[Bug 1427999] Re: purging cloud-init from user-data commands does not work under systemd

[Launchpad Bug Tracker]

This bug was fixed in the package autopkgtest - 3.11.1

---------------
autopkgtest (3.11.1) unstable; urgency=medium


  * Fix autopkgtest-reboot to also work when being called through sudo, and
    for forking test scripts.
  * Avoid failure if /var/cache/apparmor/click-ap.rules does not exist any
    more after a reboot, like on snappy.
  * adt-buildvm-ubuntu-cloud: Avoid cloud-init's prerm stopping cloud-init's
    services while we are still running them. This makes it possible to purge
    cloud-init from user-data, and avoids killing apt/dpkg underneath us. This
    needs a cleaner solution, but is a good enough workaround for now.
    (LP: #1427999)
  * adt-buildvm-ubuntu-cloud: Don't wait between serial console reads while
    we have data. Provides faster/smoother output in --verbose mode.
  * ssh-setup/nova: Fix error message on missing keypair, the command is
    "keypair-add", not "keypair-create". Thanks Thomi Richards! (LP: #1428433)
  * adt-buildvm-ubuntu-cloud: Add workaround for recent cloud-init regression
    that disables ssh (LP #1428495)
  * adt-run: Suggest common reason for unsatisfiable test dependencies.
    Suggest using a current image, or run apt-get update/-U (for apt-get) or
    --setup-commands ro-apt-update (for temp dir install mode). (LP: #1425682)
  * Quiesce confusing "failed to create symbolic link
    /sbin/autopkgtest-reboot" warning on read-only testbeds.

Bug description:
  Apparently yesterday the cloud images at http://cloud-
  images.ubuntu.com/vivid/ were switched to boot with systemd, with
  init=/lib/systemd/systemd . 20150303/ still worked (with upstart),
  20150304/ hangs:

  and there it hangs. When trying to boot, it tries to talk to
  169.254.169.254 which times out.

  The initctl emit failure looks related, this obviously won't work
  under systemd. This probably needs to be replaced with some "systemctl
  start ..." equivalent? Note that you can test for systemd with [ -d
  /run/systemd/system ], that's the canonical test.
