-#nix #flake
-
----
-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
-
-The feature can be enabled in `~/.config/nix/nix.conf`:
-
-```
-experimental-features = nix-command flakes
-```
-
-To initialize in a repo: `nix flake init`.
-
-In flakes dependencies have to be specified explicitly and MUST be locked to specific versions therefore it's no longer allowed to use the nixpkgs found in `NIX_PATH` by referencing it like `<nixpkgs>`.
-
-Output of a Flake is an arbitrary [[Zettelkast/Index/Nix]] value such as a package, [[NixOS]] module or library function.
-Commands `nix build` and `nix shell` will build the output `packages.<system>.default` unless we specify another output, for example: `nix shell .#checks.aarch64-linux.build`.

-#nix #overlay 
-
----
-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.
-
-We can use it to override existing packages or add new packages.

-#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.
