[Bug 923876] Re: FR: Limit and clean-up kernel images and headers automatically

[Steve Langasek]

This is marked fixed because the bug that was preventing kernels from
being marked as ok to clean up *in the future* has been resolved.  This
doesn't change the fact that kernels which were previously marked as
not-auto-installed are still marked that way on the system; there's no
way to safely undo that.  Users who care about this will still need to
remove the old kernels on a one-time basis.

And it's fixed in quantal because there's nothing LTS-specific about the
problem, the problem is just more severe in an LTS.  Fixed the bug
description accordingly.

** Summary changed:

- FR: Limit and clean-up kernel images and headers automatically in LTS
+ FR: Limit and clean-up kernel images and headers automatically

Bug description:
  Question #186146 is one among multiple where user unintentionally collects multiple kernel images in particular with LTS. There is no hint from relevant package management application GUIs which advise to clean up those images. With future LTS support of five years the issue presumable will extend.
  Expected.
  After installation of a newer kernel image ask the user if previous kernel images should be removed.
  Checkbox: yes - no
  If yes, offer a list of installed kernel images, don't list the one booted. Advise to keep at least the last functional one.
  Also remove -headers.

  Perhaps an additional consideration for the blueprint.
