Another challenge which has been mostly hand-waved away at this
stage is the distro support piece. Queens is being tested on Ubuntu
16.04 but our "S" release will likely be tested on Ubuntu 18.04
instead... so effective testing for a skip-level upgrade between
those two LTS releases will _also_ involve in-place upgrading of
Ubuntu.
