What I refer to as "kernal stacking" is the fact that with every new updated issue of the kernal, the prior kernal is NOT removed or overwritten. But remains in a bootable state as GRUB would have it. So my boot options are many and varied until I manage the packages manually ( ie: remove ). This is a developer service which I unintentionally evoked upon configuring for the first time. I probably agreed to it for the reason I thought I had a sketchy system. ( PC )
