Is `--upgrade` pointless when using `nixos-rebuild` with flakes?

Help

just the title. an example would be running nix flake lock --update-inputs nixpkgs: would nixos-rebuild switch upgrade all of the packages for my system based on that updated input? or would i still need to specify the --upgrade flag?

i’ve always used it since i transferred everything over to flakes, but i was thinking about it and wondered if it would even matter since everything is evaluated from the inputs. thanks for any responses!

You’re correct, you don’t need that flag anymore when using flakes. That flag was just a way to do essentially nix-channel --update nixos before the rebuild, but since you no longer are using the channel with flakes it’s not necessary.
