@raito Thanks. Running `flake update` defaulted to using the first revision in that list but that leads to a lot of building on my MacBook. Any idea how I use a different revision from the Hydra build history? It seems I need the SRI hash but I can't find it anywhere on the Hydra build pages.
@abnv apologies I don't have the flake CLI in mind but you can do something like github:nixpkgs/$revision and let nix flake lock --update-input update the SRI hashes for you
@raito Thanks, that worked! I used one revision before the latest and there was no building. It's a pity that I have to do this manually though instead of `flake update` taking care of it automatically.
PS: the flake URL syntax is `github:nixos/nixpkgs?rev=$rev`.

@abnv I guess it's a bit out of scope for flakes because they do not have the semantics of our nixpkgs channels unfortunately.
@raito which semantics are you talking about? Maybe I can write a script to automate it with flakes.
@abnv a revision completely built by Hydra vs a revision not completely built by Hydra, etc.
a revision completely tested by Hydra, etc.
