 Nix flakes are source trees containing a file `flake.nix` at their root. The file `flake.nix` provides a standardized way to provide [[Zettelkast/Index/Nix]] artifacts. It's like a package manager for [[Zettelkast/Index/Nix]]. A flake can be dependent on other Flakes and it's possible to pin dependencies to exact revisions by using a `flake.lock` file.
 
 Nix flake evaluation is hermetic, meaning that it produces the same result wherever it's built.k

+Functions that accept two args (conventionally: final, prev) and return a set of [[Package]]s.
 
 The `prev` arguments holds the set of packages of the "parent" overlay while the `final` argument holds the end result of **all** overlays applied. This means that overlays depend on each other. It is unclear how we can tell on which overlay an overlay depends.

+#nix #keyword

 The import keyword brings a Nix expression from another source into scope such that we can reference it. For example, we can `import <nixpkgs>` and it would bring the entire attribute set that is Nixpkgs into scope and allows us to reference any of its attributes.
