  Old kernels are not removed and horribly clutter the system

Bug description:
  I've been bitten twice by this - old kernels are not removed, slow
  down dpkg and use tons of space. As an example:

  vasil at shrike:~$ wc  -l /var/lib/dpkg/info/*2.6.28*list
     5656 /var/lib/dpkg/info/linux-headers-2.6.28-15-generic.list
    10357 /var/lib/dpkg/info/linux-headers-2.6.28-15.list
     2609 /var/lib/dpkg/info/linux-image-2.6.28-15-generic.list
       65 /var/lib/dpkg/info/linux-restricted-modules-2.6.28-15-generic.list
    18687 total

  So, from about 120k installed files one kernel takes 18k - a few of them can already use as much files in the dpkg database as the rest of the installed packages. Ubuntu updates its kernel at least 5 times during the normal distribution life, and some of us have stuff running since the dawn of time, so this starts to become a really nasty slowdown...
  (and, there's also bug #414943, old kernels might be a really bad idea for some people)
