Bug Description

=== Begin SRU Information ===
[Impact]
 * When landscape-client is installed in an image (default for ubuntu cloud
   images) there is a potential race where cloud-init will update the
   /etc/landscape/client.conf after landscape-client has started. If it
   does so, then landscape-client will not register until the next reboot.
 * The fix here is simply to restart lanscape-client after writing config

[Test Case]
 * This is a race condition, so it will not always occur, but generally you
   can see it by launching an Ubuntu cloud image, and providing it with
   lanscape-client configuration like the user-data below, and then expecting
   that system to correctly register itself.
   #cloud-config
   apt_upgrade: True
   apt_sources:
    - source: deb $MIRROR $RELEASE-proposed main
   landscape:
     client:
       url: "https://landscape.canonical.com/message-system"
       ping_url: "http://landscape.canonical.com/ping"
       data_path: "/var/lib/landscape/client"
       http_proxy: "http://my.proxy.com/foobar"
       tags: "server,cloud"

[Regression Potential]
 * landscape-client could not behave well when 'restart' is requested
   right after it had started. If that was the case, this could result
   in a race where the fix didn't actually accomplish what we wanted.
 * There is very little potential for regression other than in the
   case where the user was trying to register instance with landscape.

=== End SRU Information ===

After installing landscape, or otherwise configuring it, cloud-init needs to restart the service.

This bug was fixed in the package cloud-init - 0.7.1-0ubuntu1

---------------
cloud-init (0.7.1-0ubuntu1) raring; urgency=low

  * New upstream release.
    * landscape: install landscape-client package if not installed.
      only take action if cloud-config is present (LP: #1066115)
    * landscape: restart landscape after install or config (LP: #1070345)
    * multipart/archive: do not fail on unknown headers in multipart
      mime or cloud-archive config (LP: #1065116).
    * tools/Z99-cloud-locale-test.sh: avoid warning when user's shell is
      zsh (LP: #1073077)
    * fix stack trace when unknown user-data input had unicode (LP: #1075756)
    * split 'apt-update-upgrade' config module into 'apt-configure' and
      'package-update-upgrade-install'. The 'package-update-upgrade-install'
      will be a cross distro module.
    * fix bug where cloud-config from user-data could not affect system_info
      settings (LP: #1076811)
    * add yum_add_repo configuration module for adding additional yum repos
    * fix public key importing with config-drive-v2 datasource (LP: #1077700)
    * handle renaming and fixing up of marker names (LP: #1075980)
      this relieves that burden from the distro/packaging.
    * group config: fix how group members weren't being translated correctly
      when the group: [member, member...] format was used (LP: #1077245)
    * work around an issue with boto > 0.6.0 that lazy loaded the return from
      get_instance_metadata(). This resulted in failure for cloud-init to
      install ssh keys. (LP: #1068801)
    * add power_state_change config module for shutting down stystem after
      cloud-init finishes. (LP: #1064665)
