Bug#275688: kernel-image-2.6-686: apt-get remove does not put back the old kernel

[Greg Kochanski <gpk@kochanski.org>]

Package: kernel-image-2.6-686
Severity: normal

I have a debian system that normally runs kernel-image-2.4-686 ;
I put in kernel-image-2.6-686 as a test via
apt-get install kernel-image-2.6-686 .
Then, when I removed it later,
via
apt-get remove kernel-image-2.6-686
the package was removed, but /etc/lilo.conf was not reconfigured
to boot the old Debian kernel.

For instance, /etc/lilo.conf is set to boot /vmlinuz, which is still linked
to the 2.6.8 kernel.   Fortunately, the backup kernel is still set to
a 2.4 kernel that exists, but it's easy to imagine someone
installing two different 2.6 kernels, removing them,
and then finding that lilo no longer knows how to boot a 2.4 series kernel.

It seems that the user could be better protected.
