So, as far as I can tell now, all I need to do is make the flake a GC root, right? So, how do I do that...

In reply to @ryoschin:matrix.org
I see. Mind sharing the process?

i've been looking into this again after some time away, and still can't really find anything:
is there a way to exclude one directory from my flake? specifically we have a giant folder of reference PDFs checked into our source tree, and copying them every time a flake is built makes our development shell unusable.
this is why we're currently running non-flake nix, but I would love to be able to switch

Everyone seems to do this differently. I have this for building NixOS configs.

{ self, nixpkgs, ... }:
(nixpkgs.lib.mapAttrs'
  (name: config: nixpkgs.lib.nameValuePair name config.config.system.build.toplevel)
  self.nixosConfigurations
)

But not sure if this actually works, or if I configured the jobs manually in hydra...

hmm, is there a more elegant solution for adding overlays in a flake than

pkgs = import nixpkgs {
        inherit system;
        overlays = [
          poetry2nix.overlay
        ];
      };

or is this just how it's done?

What is a nice way to fill hydraJobs with the packages and checks of a flake?

    hydraJobs = {
      inherit (self) checks packages;
    };

In reply to @wucke13:matrix.org
but formally packages are system.attr, while hydraJobs is attr.system

So I'm having a hard time grasping flakes and why I should start using them. I am still pretty new to nix os.

In reply to @janik0:matrix.org
they try to give you a more ore less defined api of inputs and outputs, kinda like a swagger.json for rest apis in case you are familiar but a lot more vibes and less standard. A output can be anything from a systemConfiguration, to a derivation or function. I don't know if you should start using them that's a kind hard question to answer. a lot of unofficial documentation has support and many times even better support for them because many people feel it's easier learning them. Basically anything you can do with flakes can also be done without them and for some things you need community tools like niv or npins for pinning versions.
