Comment 2 for bug 1446269

Two latest installed kernels are expected to be 'actual active' ones, not 'obsolete' like 'synaptic' shows. Or that setting should be set by the user depending on his wish.
This often happen with the devlopment ubuntu release, where there is not several kernels yet (genuine, proposed, security)

So voting to get 2 latest kernels not removed when 'autoremove' is ran.
