Removing old kernels?
 

I noticed that my kernel has been updated 3 times since it was installed a few months ago. I know how to remove the "Grub" entries from the list but I was wondering if I can or even should remove the old kernel versions that I am no longer using.

I would assume this would keep my Linux system a bit cleaner or less cluttered with having 10 old kernels that are no longer used.

I know it is good to keep the last kernel just in case I need to revert back to it for fail safe reasons.

Thanks for any info.
