This is already possible with kpatch, ksplice, etc. This new thing seems more like a hypervisor of sorts? Or maybe a next level docker where containers could package their own kernel?
In-memory kernel patching is complicated, AFAIK only select distributions support it, right? If kernel hotswap is successfully implemented this way, it should allow switching between arbitrary kernels at runtime without extra work or setup.
Of course, that’s a pretty big “if”, but a simple unified system sounds like a great thing. And of course there’s more to this than swapping kernels.
