Does that mean bootless kernel updates?
If so, between that and declarative configuration, it sounds way better than I envisioned the product was going to be.
Yeah, I think that’s what that means. How it works is that you will reconfigure your system, which will load the new version into kexec. Then you can simply launch
reboot --kexecto switch to your new system, including the new kernel.
