 Robert Hensing (roberth) | They were combined into a single change to maximize the utility of having a v2 | 16:48:05 |
| Robert Hensing (roberth) | oh that... | 16:48:28 |
 hsjobeki | Though i am not sure what the benefit of merging without checking is. Checks are usually shallow and shouldnt change the lazyness. If the value is not of the expected type, merging it would also fail | 16:50:33 |
| Robert Hensing (roberth) | If you want merging without checking, you can still construct a type that achieves that | 16:51:02 |
| Robert Hensing (roberth) | But yeah, generally the check is simple because otherwise you're inducing unnecessary strictness, as in non-laziness | 16:51:36 |
| Robert Hensing (roberth) | => infinite recursions | 16:51:54 |
| hsjobeki | Do you suspect a breaking change in lazyness between just merge and checkAndMerge ? | 16:54:48 |
| hsjobeki | We dont have any reports, or at least i didnt get pinged in any issues regarding that. | 16:55:47 |
 n4ch723hr3r | do i have to use systemd.tmpfiles? | 16:56:55 |
 Matt Sturgeon | In reply to @n4ch723hr3r:nope.chat
do i have to use systemd.tmpfiles? This room is for discussing the module system itself, not NixOS and its options. You want https://matrix.to/#/!6oudZq5zJjAyrxL2uY:0upti.me | 17:16:25 |
 vivekanandan_ks | Hi All,
What do u all think about the flake-parts?
Is that somehow making the current modules system better?
Or it helps the current modules to be easy? | 17:59:32 |
| Matt Sturgeon | Flake-parts uses the module system to construct flake outputs. Just like how NixOS uses the module system to construct an OS, or Home Manager uses the module system to construct a user's profile.
I'm not sure what you're asking about how it interacts with "current" modules, or what you mean by "current" 🙂 | 18:20:35 |
| n4ch723hr3r | i think hes asking for an opinion about flake.parts | 18:43:44 |
| 26 Nov 2025 |
| hsjobeki | I'd say i don't have a general opinion.
If you develop a third party nix library that other people depend on every input that you have adds to their dependencies as well.
That is how flake dependencies behave. And everyone needs to pin nixpkgs-lib of flake-parts otherwise you get their version, which is an extra 50MB download.
Other than that if you are using it for your own project that doesn't have dependents it is in my opinion a good UX, which lets you leverage the module system to decompose the components of your flake. | 16:33:29 |
| Robert Hensing (roberth) | it now uses a small lib-only flake fwiw, but the override still makes sense to have | 16:39:27 |

| mr-qubo | I recently stumbled upon similar issue when working on home-manager. https://discourse.nixos.org/t/is-it-possible-to-define-systemd-services-in-a-submodule/39538/5
The idea is that enabling https://nix-community.github.io/home-manager/options.xhtml#opt-programs.bash.enableCompletion should set environment.pathsToLink = [ "/share/bash-completion" ];.
I think that module system is missing an option to pass config options recursively up to all ancestors.
| 15:06:01 |
| mr-qubo | My idea is that nixos config could have a property extraNixosChildConfig and in home-manager bash module I could set _recurseAncestors = { extraNixosChildConfig = { environment.pathsToLink = [ ... ]; }; }. | 15:07:22 |
| mr-qubo | wdyt? | 15:07:26 |
| mr-qubo | * My idea is that nixos config could have a property extraNixosChildConfig that gets merged with the rest of the config and in home-manager bash module I could set _recurseAncestors = { extraNixosChildConfig = { environment.pathsToLink = [ ... ]; }; }. | 15:07:44 |
| mr-qubo | * My idea is that nixos config could pick up extraNixosChildConfig from childs and merge it with the rest of the config and in home-manager bash module I could set _recurseAncestors = { extraNixosChildConfig = { environment.pathsToLink = [ ... ]; }; }. | 15:08:21 |
 infinisil | Not sure about that recursive thing, that doesn't seem necessary, but yeah if there's something missing in the NixOS module for home-manager, that could be added | 15:34:09 |
| infinisil | Sounds like an issue for the home-manager repo | 15:34:16 |
| mr-qubo | Yeah, we could add it just for home-manager. But is seems like the issue is quite generic. See also https://github.com/NixOS/nixpkgs/pull/152785. | 15:51:50 |
| infinisil | Hmm yeah fair. I don't have the capacity to think a lot about this right now, it's a very intricate topic to wrap ones head around | 15:56:55 |
| mr-qubo | Yeah, I just wanted to bring the topic, maybe someone has some interesting thoughts. | 16:05:23 |
