-		- For NixOS configurations you generally care only about the `Size` (closure size/size on disk).
-		  - Reduce the `Size` by disabling unneeded services/default packages.
-		- For Packages you care about both the `Size` and the `NAR Size`.
-		  - Reduce the `NAR Size` by reducing the size of the build outputs, e.g. don't copy unnecessary data to the $out dir, optimize binaries for size, etc.
-		  - Reduce the `Size` by reducing the dependencies (e.g. `buildInputs`).
-		  - Don't worry too much about size, some dependencies are deduplicated, e.g. `glibc` adds ~40MiB to the `Size`, but is generally shared by ~every binary on the system, so, chances are, you are already including it from somewhere else and statically linking with e.g. `musl` is not gonna improve things.
