I have 4 kernels in /boot, leaving on 20MB which is not enough for the

I had installonly_limit= set at 5, as there were some kernel problems.
After I got the error that there was not enough room for another kernel,
I set installonly_limit= to 3 and did the update with --exclude=kernel*

That worked to update everything else, but not remove the oldest kernel.

How can I remove the oldest kernel to make room for the new one?
yum remove kernel-rest-of-kernel-name, for example
yum remove kernel-3.10.0-862.2.3.el7.x86_64

# yum remove kernel-4.14.28-201.el7.centos.armv7hl

Is this ok [y/N]:

Only freed up 12MB.  All the other kernel components are still there:

How do I get rid of the whole lot?


thanks
