Notes

RFC 140

Checking for package collisions:

$ nix repl -f https://github.com/NixOS/nixpkgs/tarball/master
Added 19084 variables.
nix-repl> lib.foldl' (acc: el: if lib.toLower acc == lib.toLower el then builtins.trace "${acc} <-> ${el}" el else el) "" (lib.attrNames pkgs)
trace: antimicroX <-> antimicrox
trace: flameGraph <-> flamegraph
trace: vkBasalt <-> vkbasalt

But these are all aliases of each other, so no problem

• Steering committee status unclear, so went ahead and had the first meeting with nominated shepherds.

• Made changes before and after the meeting to address concerns and clean it up

• Tested backporting, works without problems

Packages modules WG

• Regular meetings happening!

• A few pull requests open

• meeting notes in pkgs-modules repos.

Misc: super pure bootstrap from GUIX

• https://guix.gnu.org/blog/2023/the-full-source-bootstrap-building-from-source-all-the-way-down/

• Emily Trau got started on doing this for Nix. NixOS/nixpkgs#227914 --- first PR, and follows ups also linked there.

• Great foundation for Nixpkgs Architecture experimentation because it is entirely self contained

• binary blogs, coarse-grained things like stdenv make more more mass rebuilds / friction / ineritia.

• @roberth also mentioned, good place for not exposing all attributes, see also nixpkgs cleanAttrs PR

• No need for action, but should keep an eye on it, potential stdenv rewrite using it as a base

• derivationWithMeta for the win! It is good to separate the meta checking infra from the rest of stdenv.mkDerivation
