I love focking #nix.
Tried to setup nix-darwin from my big infra repo with working configs for about 3-4 nix machines and got extremely strange error about non-existence of secrets folder, which i include as submodule.
In the result: all prod runs nix 2.18 or older.
My mac had nix 2.20.
They broke ?submodule param in 2.19.
