Removing native kernel
So, I have installed a new kernel using apt-get install kernel-image-x.x.xx and everything seems to be working fine. Now, the old kernel is still on my system. Since space does matter on my ancient i486, I am considering removing some files.
The old kernel was the native kernel of the installation image. So removing this kernel can't be done by just doing apt-get remove kernel-image-x.x.xx. This package simply doesn't exist. So, how can I remove the files associated with this kernel? If I need to do that manually, which are the ones to remove?
I know it is wise to keep at least one old kernel for emergencies, however can I cut down the number modules by deleting the unused modules in older kernels? What about the redundant modules for the new kernel? Can I remove them as well?
I guess these are very newbie questions. I hope someone can help me out on this downsizing issue.
