Agenda

Notes

  • @Ericson2314: PR count is currently below 300 at last, somewhat good result
    • Though still would want it to be much lower
    • @fricklerhandwerk: PRs are not necessarily a meaningful metric, lots of noise in there
      • inbox zero may be desirable in general, but we don’t have any chance to brute force the problem in any case
      • we have to continue finding and addressing the underlying issues first

Make `initLibStore` a viable alternative by roberth · Pull Request #7732 · NixOS/nix · GitHub

  • Merged
  • We can not be 100% sure beforehand whether slightly changing the order of things is fine, but that’s OK.

  • Right after a release (2.15) gets us plenty of time to find out
