I have opened a couple of bugs you can include in the changelog for easier release team acceptance (remember the distro is in freeze right now):

• https://bugs.launchpad.net/ubuntu/+source/adsys/+bug/2037270
• https://bugs.launchpad.net/ubuntu/+source/adsys/+bug/2037271
  Mind including them? Then, all good, you can merge, thanks for tackling all this! Let me know once I can sponsor it :)
