Ignoring the reboot doesn’t work when it’s a reboot to the Nvidia driver, as I’ve found out. The displays will work but Vulkan/OpenGL will break in confusing ways with error messages that point in the wrong direction.

I don’t really understand why more Linux don’t hot replace the kernel, Ubuntu can do it and so can a bunch of enterprise Linux variants. I assume there’s some kind of design limitation that prevents other distros from using that API.
