Kernel Crud Delete Mode for Opti

Sort of an emergency kernel deletion...
It belched an error upon installing the newest one, because of lack of HDD space (I'm a such a schmuck!).
So, immediately I deleted old ones (Some 800 MB of HDD reclaimed), and executed once again the updater, but it belched once more...
Nevertheless, rebooted the box, and everything is A Ok, using the latest kernel.
