Bug Description
[Impact]
* Minimized images have their disk footprint further reduced with these
changes.
* Using minimal images can save bandwidth and system resources and we
would like to make those improvements available for Xenial users,
especially since most if not all of our minimized images users care
mostly about LTS releases.
[Test Case]
* No new autopkgtest was added, however, an autopkgtest (minimized)
was previously added to test building minimized images. The test logs show
the generated image sizes for ubuntu-cpc images with and without
minimization and the minimized images have to be smaller.
[Regression Potential]
* If images rely on the presence of a populated /var/cache/apt, that
functionality could now break (no such image is known). This is believed
to be a functionally "no-op" change.
* If images rely on /var/cache/
be present, that functionality cloud now break (no such image is known).
This is believed to be a functionally "no-op" change.
* The package changes should not affect images which are not minimized. The
minimized images in general may not boot on some systems. This is not a
regression however, this branch does not make the situation better or
worse in this regard.

"Regression potential" section is inaccurate, there are changes here that remove files from all images and a change which should be a functional no-op that is applied to all image builds. We should have some analysis here of what a probable regression from these changes would look like.
