Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
nixos-configs
- My First Impressions of Nix

How does the workflow look with flake based config?
If you put your flake in a Git repository, you can reference the repo without having to clone it by using a flake reference syntax. I keep my flake in GitHub, so I use github:reckenrode/nixos-configs to reference it when running nixos-rebuild, etc.
-
What has your experience been with system.autoUpgrade? (optionally, with flakes)
I use a GitHub action to run nix flake update nightly to bump my flake. My systems are set to update nightly (rebooting as necessary). It’s bee mostly free of problems. I did lose my Raspberry Pi 4B+, but that was a pretty hacky set up, and I didn’t bother to dig into why it stopped booting. Otherwise, it’s been pretty smooth. The only time I’ve needed to boot into a previous generation was when I botched some config changes when updating to a new NixOS release.

Off-the-shelf NAS supporting NixOS
I’m running NixOS on a QNAP TS-453D. I wiped the software that came with it and run on the bare metal. I’ve added 16 GiB of RAM and an AX210-based Wi-Fi card to it. Everything works pretty well with three 16 TiB SeaGate Ironwolf Pro drives on ZFS and an SSD for the NixOS install itself. My NixOS config for it is here.
-
setting up dxvk on nixos
DXVK is available in nixpkgs. If you install it, it provides the setup_dxvk.sh script to inject DXVK into a Wine prefix. For an example of a derivation that sets up a prefix and copies the DLLs into it manually, see the FFXIV derivation in my configs.
-
Sharing configuration between NixOS and MacOS
There are my configs: https://github.com/reckenrode/nixos-configs.
-
DXVK 1.10 for Mac
Thanks for the clarification. I think our goals are just divergent. I’m looking for something that uses the packages in nixpkgs and integrates nicely with my nixos-configs, which I use to declaratively manage my macOS environments (none of my Linux systems are capable of running the game).
-
Flake structure for multi system
My flake does most of those things. I don’t have any systems with WSL, so I’m not sure whether or how that would work. If it can be created by nixosSystem, then it would probably work. I take a pretty different approach in my flake though. I’ve structured it so I can define platforms, hosts, and users by convention. Adding a new host is just creating the right directory and dropping a configuration.nix in it. Still, that might not be helpful for your needs since you’ve already got an established convention.
-
How to use different channels in a flake to configure NixOS?
I make use of multiple channels in my nixos-configs. Instead of using overlays, I pass them as specialArgs to the system build function (e.g., lib.nixosSystem). That lets me reference them in my configuration as just another set of packages (e.g., I reference flake-specific packages, unstable packages, and x86_64-darwin packages here). Note that you also need to pass them as extraSpecialArgs to your specialArgs to access them from your Home Manager configuration.
-
Stuck in migration to flake for configuration.nix
The way I handle it in my configs is to add unstable as an attribute via an overlay. If I need a package from unstable, I can use it via pkgs.unstable..

Looking for dotfiles repo examples
This one issue may clear things up, seems like my config is a little outdated: https://github.com/divnix/digga/pull/385
-
Building a highly optimized home environment with Nix
I'm new to the Nix world, but so far I've come across Divnix's Digga, Numtide's DevShell, and Misterio77's nix-starter-configs.
-
Need for a configuration framework?
There are config templates / configuration helper libraries that try to make this easier, for example digga/devos.
-
(meme) It's a temporary setback really
https://nixos.wiki/wiki/Flakes, especially the “see also” section. If you’re looking to use for NixOS config across multiple hosts, digga (see the repo for example template) is pretty nice for encapsulating a lot of boilerplate.
-
Sharing configuration between NixOS and MacOS
The digga library, while being more complex to use than other solutions here, got a pretty elegant solution for it merged a few weeks ago. Still some cracks that are getting smoothed over, but it seems to work.
-
Best practices for organizing code repository for multiple machines? What about deployment?
I like the concept digga/devos uses (unfortunately their stuff kind of is an overengineered incomprehensible mess): They use: - modules: for modules like in nixpkgs (i.e. stuff that defines options and generates configuration based on that options; are included into every host) - profiles: concrete configuration, can be included to host definitions - suites: sets of profiles (so you can for example have a desktop suite with all your profiles with "desktop" configuration options and apply that to all your desktop computers)
- Nix: An idea whose time has come
-
The Curse of NixOS
For the system, I like the devos template:
https://github.com/divnix/devos
The idea of flakes is how you define inputs, and you define the system (and packages, and shell etc.) in the outputs using the inputs. The inputs are git repos which point to other flakes. You can mix and match these as much as you want (see the devos repo for examples) and when you build the derivation, it generates a lockfile for exact commits in that point in time what were used in the given inputs.
You commit the lockfile and in the other systems where you pull your config from the repo, it uses exactly those commits and installs the same versions as you did in your other systems.
This was quite annoying and hard to do before flakes. Now it's easy.
The problem what people face with building their system as a flake is combining the packages so you can point to `jq` from the unstable nixos and firefox from the stable train. I think this aspect needs better documentation so it wouldn't be so damn hard to learn (believe me, I know). Luckily there are projects like devos that give a nice template for people to play with (with documentation!)
Another use for flakes is to create a development shell for your repo, an example what I did a while ago:
https://github.com/pimeys/nix-prisma-example
Either have `nix-direnv` installed, enter the directory and say `direnv allow`, or just `nix develop` and it will gather, compile and install the correct versions of packages to your shell. Updating the packages? Call `nix flake update` in the directory, commit the lockfile and everybody else gets the new versions to their shell.
-
What's the proper way to set up nix / home manager w/ flakes, directory wise?
Yes, I put the repository in ~/nix. My repository is based on devos, but I am thinking of switching to a different setup, because I don't want to depend on a framework which can be an issue in updating.
-
The future of Home Manager and Flakes
I no longer use the official way since I have switched to flakes. I am currently using a devos-based config, which is a boilerplate that depends on a Nix toolchain, but I plan on rewriting the config with flake-utils-plus. You probably can install home-manager using deploy-rs. See the following comment:
