Comment 27 for bug 1922739

I'm performing verification of this locally using the cloud-init integration testing framework. Specifically, I'm running test_upgrade_package[0] with the following diff applied (to trigger this bug):

     with session_cloud.launch(launch_kwargs=launch_kwargs) as instance:
- instance.install_deb()
+ instance.install_new_cloud_init(source, take_snapshot=False, clean=False)
         instance.restart()
         assert instance.execute('cloud-init status --wait --long').ok

The important changes here are that I can run it against both the release pocket and -proposed, and that it doesn't perform a clean any longer. I'll propose these changes to cloud-init upstream after validation is complete.
