Speaking of kernels... I have the toughest time trying to remove the older ones to clean up some storage space.
Before this latest install, the partition I used for the kernels was only about 100MB.. I found out it was full when it wouldn’t update to the latest, and I had no way to clean it out x.* (I made that partition MUCH larger this time.. but still trying to find the best way to clean out the older kernels.. I have about 15-20 in there now :p )
The best way I've found to clean up old kernels is not something Mint has available--rpm, package-cleanup, and yum.
I can't help you with Mint, though :(
I just saw yesterday that “mintUpdate” update manager, when I click on “View” the pulldown menu has an option for “Linux kernels”. You may find your answer there.
