This is something that has been puzzling me but I have not had a
chance to look into it except for checking the above file and some
others in apt.conf.d.

Since starting to use Lucid, aptitude has been uninstalling kernels
automatically and leaving me with just two kernels at every kernel
update. I had meant to look into the logs but I forgot about it and
did a clean install two days ago.

Has anyone else run into this? NoOp?
