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

[Jarno Suni]

As for apt, does the fix offered to this bug mean that you can upgrade by 
sudo apt-get dist-upgrade
and have no fear of /boot getting full?

Anyway, I suppose this method of upgrading will work now for the issue in Trusty and later:
sudo apt-get dist-upgrade --auto-remove --purge

sudo apt-get autoremove 
may also remove other packages besides old kernels and related packages, but maybe that is not bad thing.

If I install a kernel manually by `apt-get install`, it will be marked
as "manual", and will not be removed by `apt-get autoremove`, unless I
run `apt-mark auto` for it first. Isn't is bad to skip removing any
manually installed kernels? Would it be better to skip only kernels
marked as "hold"?

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.
