It’s a little more effort to maintain compared to something like nix, but Arch (including CachyOS) doesn’t have the same config drift problem as distros like Debian, because it has pacdiff to let you consolidate any updated defaults with your own settings.

It’s literally just picking which snapshot you want to boot in the boot loader and then accepting the prompt to make that one the new default after you’ve verified it works. It’s not possible for old binaries to be running.
