Why does grub store multiple kernels?

rated 0 times [ 13] [ 0] / answers: 1 / hits: 2723 / 2 Years ago, sun, august 21, 2022, 12:57:29

Is there some sort of best practice around removing them (when/how/why)? What is the point of keeping them around in the first place and why would you even put them in grub?

I guess there is not a "problem" per say, but I am just curious about that design decision.

Correct me if I am wrong, but you can still use the old kernels with the new user interface right?

The short answer is they are used "as a backup". New kernels are tested on a large amount of hardware before being released, but can't be tested on everything. If an update causes the machine to not boot successfully, then the previous known-good kernel is available as a fallback.
