#04 - Everything not saved will be lost

Nix, NixOS and nixpkgs are all moving ahead at good speed. The 17.03 milestone is more than 50% complete, and we merged 144 pull requests for nixpkgs just in the last seven days.


  • The NixOS 17.03 beta has been announced.
  • We now allow packages to be marked insecure, and you have to opt-in to install insecure packages similarly to how you opt in to non-free software. The option is called permittedInsecurePackages. See the updated docs for more.
  • Robin finished the systemd 232 update which opens up several new opportunities for hardening. It will also allow us to move away from hard-coded user IDs for less important services. Just use DynamicUser = true.
  • Thanks to Graham we now have aarch64 support, and it’s even being built by Hydra! Many of you will have noticed already from the beautiful stream of emails for each succeeding and failing package.
  • Progress on the proposal for RFC which started from a FOSDEM discussion.
  • Move NodeJS to separate overlay repository? (discussion)

Editor’s corner

First time run for me to take care as the editor for an edition of [NixOS Weekly]{.title-ref}. It has been fantastic to see a few people spontaneously helping out to make it happen after a call for help from Rok.

Contributions are easy: Send a pull request to the repository or comment on the open issue for the next edition by providing a hint regarding a presentation, an event, a relevant change or discussion.
