I just installed the new kernel on one of my Cubieboard2s. /boot used grew ~130MB.
Challenge is that my next board to update only has 43MB free. It currently has 3 kernels on it.
Is there a way to cleanly delete old kernel files prior to the update? In this case 4.9.30-203?
Are you meaning something like this?

Did nothing. Just came back to the # prompt. And no reduction in space used in /boot and no change in 'ls /boot'. Or at least what I noticed.
Then you need to use the du command and see what is using up the space. Also check to make sure that the size is the same as the other systems to see why they have different amounts.
kernels for armhfp come in 3 parts (or more), there is kernel, kernel-core and kernel-modules, so you need to remove all those 3 for each kernel in order o actually free space.
