Pretty sure this is exactly what the “immutable OS” is for, like what’s found in Fedora Silverblue (and less notably in the SteamDeck).

It essentially lets you break whatever you want in userland, but it mounts the root filesystem in read-only, and literally re-images the entire machine each update w/ the added bonus of halting and rolling back the update if any errors are detected during the update. All of which occurs “magically” behind the scenes upon shutdown, so it requires essentially little to no user interaction to manage core updates.

Also all graphical software is limited to flatpaks, so you really take out a lot of the user confusion about installing on Linux and dealing with system-specific weirdness.
