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.






If I understand correctly, it’s a different kind of “immutable”, since distros like Bazzite provide premade immutable images you use and anything else you need you install using alternative means, whereas NixOS is an immutable image generator that requires you to set up your own definitions for the image, but also lets you install software by adding it to that image.
