Too many old kernels are installed

[phmccarty]

Describe the bug
Upon inspecting a Clear Linux system today, I noticed that there may be too many old kernels remaining on the system. The system uses kernel-lts exclusively, but there are several kernel bundles actually installed.

Steps to reproduce
This problem is not happening on other systems that I've checked. If I discover more concrete steps to reproduce, then I will post them at a later time.

Expected behavior
I expected to see older kernels removed from the system as below:

• All lts2018 kernels older than latest, since these kernels are no longer used. They stopped being used after kernel-lts switched its bundle include from kernel-lts2018 to kernel-lts2019.
• All lts2019 kernels older than latest, except for the currently running lts2019 kernel, if it differs from latest
• All native kernels older than latest, since these kernels are not used.
• All preempt_rt kernels older than latest, since these kernels are not used.
