There are ways to secure the update process. For example, you can enable secure boot and store your secure boot keys encrypted (or on a smart card). Then (if a full chain of trust is implemented) to update your system, you'd need to enter the private key password (or insert the smart card), and a root-access executable couldn't to that automatically.
Yeah, but do other distros do this though? Not that I'm aware.
And surely the same could be done to NixOS, no?
I think it can in theory, but there will be some problems. But most likely Silverblue or something else would have its own problems trying to implement something like that - I don't have any experience with them and don't know how they'd compare.
