My oldest (2008) computer just became free for 'experimentation'. After 12+ years of running Mint I decided to install Zorin Core. It all works as well as I had hoped; I'm a little surprised to find that the kernel level in use with Core 16 is 5.11, where as I was advised, just a few months ago, when using Mint on this computer, that I should be using kernel version 5.4 for such old hardware. is this not true for Zorin OS?
I also notice that multiple releases of a given version of the Linux kernel are not installed, as they are in Mint. Does Zorin automatically delete obsolete kernels? Can I indeed revert to an earlier kernel version?
