[Bug 1731492] Re: [SRU] Release "minimized round 2" changes to Xenial
This bug was fixed in the package livecd-rootfs - 2.408.24
---------------
livecd-rootfs (2.408.24) xenial; urgency=medium
* For the IMAGEFORMAT=none parts to work for ubuntu-image classic builds, we
need to make sure IMAGEFORMAT is preserved and not overwritten if defined.
Backporting from artful.
livecd-rootfs (2.408.23) xenial; urgency=medium
[ Gary Wang ]
* Add the IMAGEFORMAT=none to support generating a single rootfs
(LP: #1730642)
[ Christopher Glass (Ubuntu) ]
* Backport "minimized round 2" changes from trunk to Xenial (LP: #1731492)
* Remove apt, debconf, dpkg cruft files from /var/cache and /var/lib in
all our livefses.
* Pass --cache false to lb config; otherwise we copy around caches of
.debs that are never used properly, and which prevent us from emptying
/var/cache/apt in images.
* When building minimized cloud images, remove various packages that we
don't want installed by default. Some are tools that aren't needed for
non-interactive use; some are libraries whose reverse-dependencies
will have already been removed; and one, open-vm-tools, should only be
included in images that are targeted to VMWare (which is not the case
for any of the current minimal images), rather than being included
directly in the cloud-image seed.

Title:
[SRU] Release "minimized round 2" changes to Xenial
Status in livecd-rootfs package in Ubuntu:
Fix Released
Status in livecd-rootfs source package in Xenial:
Fix Released
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/debconf/*-old or /var/lib/dpkg/*-old files to
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.
