Flake output sizes

Definitions
  • Name: the name of the package/configuration.
  • Size: the closure size (size on disk/NAR size + all transitive dependencies).
  • NAR Size: the size of the build output (package without the dependencies).
  • [NAR] Size Change: the amount changed compared to the main branch.
Tips on reading this data
  • For NixOS/Home-Manager 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.
