#nixos is somewhat of pioneer in the space of reproducible builds and is 20 years old

For the #NixOS #QubesOS and #reproduciblebuilds nerds out there, I finally found some time to clean this up enough for post my fully-reproducible NixOS template for QubesOS PR: https://github.com/evq/qubes-nixos-template/pull/7

This feels so niche it kind of hurts my soul. FWIW I'll do a lightning talk on the value of build reproducibility on Thursday, so maybe I can get a few more people to care.

I do love when I fall into rabbit holes, kind of, but today's excursion got unhealthy. As in I barely did any of the things I was supposed to do, or meant to do.

FWIW, I got a fully reproducible (as in byte-reproducible) #NixOS #QubesOS 4.3 template working. Well, working is a bit of an overstatement but I got as far as this.

Most of the work was done by evq here https://github.com/evq/qubes-nixos-template I just banged my head against the wall until my ancient memories of Qubes OS internals bubbled up, and got interested in how reproducible ext4 images could work. Anyway. I'll assemble an in-depth PR some other time (tomorrow is travel day), but I've wanted this since 2022.

There, that's one type of neurospicy that I am 🤦

I've updated Wombat's Book of Nix

As usual, of course migrating services is also possible with other distributions, but the experience is very predictable and smooth with #NixOS and I did not have to distinguish between self-packaged custom Go software or distribution-provided standard FOSS software — it can all be moved around easily, including not just services, but also system users/groups, auth keys and other secrets, and PostgreSQL databases (config, not contents).

For two VMs, I could just live-migrate them between hypervisors, but the third one runs Caddy and hence needs DNS updates for each service, so I did a service-by-service migration.

This is where migrating to #NixOS has paid off: I could migrate a setup spanning 4 custom Go services, 17 virtual hosts, totaling 25 .nix files from one server to another in just about 2 hours.

The trivial approach of “move config, deploy dest, stop src, copy state, update DNS, deploy src” worked beautifully :)

A new module is available: `programs.swappy` Swappy is a Wayland native snapshot and editor tool, inspired by Snappy on macOS. Works great with grim, slurp and sway. But can easily work with other screen copy tools that can output a final image to stdout.

Submaps allow you to create keybind contexts in Hyprland, useful for creating mode-based workflows like resize modes or application launch menus. Configure submaps using the new 'submaps' option: wayland.windowManager.hyprland.submaps.resize = { settings = { binde = [ ", right, resizeactive, 10 0" ", left, resizeactive, -10 0" ", up, resizeactive, 0 -10" ", down, resizeactive, 0 10" ]; bind = [ ", escape, submap, reset" ]; }; }; Learn more about submaps at: https://wiki.hypr.land/Configuring/Binds#submaps

#NixOS will probably be great - 10 years down the line - as the Nix community has to both maintain a massive assortment of packages WHILE refactoring #Nix & #Nixpkgs according to their RFCs.

I think the idea is to take enough functionality out of nix and into nixpkgs, to the point where they can offer an enterprise edition of nixpkgs. #Flakes also needs to be replaced, apparently.

I got #NixOS to work on my Wii-U!!

Finally switching my #NixOS server configuration to use nix #flakes. Also I'm installing #sops and nix-sops to handle secrets properly encrypted. It's long overdue.

Are there some easy examples for #nixpkgs?

I'm currently failing at figuring out how to properly add a dependency to a package so that I can access a file from the dependency at runtime from the actual package at a specific location...

#NixOS #Nix #HomeManager

How do I install a package from my local checkout of my (modified) fork of the nixpkgs repo so that doing "nixos-rebuild switch" will overwrite these changes?

Currently the docs just say to use "nix-env -f . -iA libfoo" but so far everyone told me to NEVER NEVER EVER run "nix-env" as this will "fuck up the entire system in a way that nixos-rebuild won't fix".

#nix #nixos #nixpkgs

Is there some documentation for which "NixOS tests in nixos/tests" I've to run when I'm trying to make a PR to nixpkgs for a single package?

At most I was able to find how to run a test but not anything in regards to which one(s).

Also as there are literally countless dedicated tests and I don't want to accidentally run one that locally rebuilds every single package the trial-and-error approach also kinda isn't fitting.

Also which of these does the CI/CD (also) run?

#nix #nixos #nixpkgs

googling for how to update the checksum in a #nixpkg is surprisingly difficult. You get more incorrect solutions than search results.

Why can't you just use a normal sha256 of the exact file downloaded from the url that is literally right above it?

PRO TIP: when creating a configuration to install with nixos-anywhere[1], make sure you include some form of root access! (unlike me today )

I suggest setting users.users.root.openssh.authorizedKeys.keys to some sensible value. Alternately, you could set a user password with mkpasswd as described below, and make sure you have that user account in the wheel group.

Meet Kiki! My Framework 12 laptop arrived just last week, to replace my aging Thinkpad X250. It's been a really nice laptop so far, and the installation and use has been very smooth. From first impressions I can absolutely recommend it.

Fixed Output Derivations
#nixos

Normally, Nix doesn’t allow derivations (= build steps) to access the network2.

If you want network access from a derivation to download some sources, Nix requires you to set clear expectations: an output hash. A derivation with such a predetermined output hash is called “Fixed Output Derivation” or, abbreviated, “FOD”.

This prevents you from silently introducing randomness into your build. If you interact with the network, you interact with the messy world beyond Nix’s control. But, at least, Nix can shout and abort the build, when your derivation does not produce the expected output.
Enter caching (substitution)
Nix will helpfully cache the result by the name of the derivation and the output hash.3 You have given Nix a promise: Trust me, whatever command I specify, it will result in the given hash. If Nix can ascertain the right result, why do all the hard work?
https://blog.eigenvalue.net/nix-rerunning-fixed-output-derivations/

What #nix (and #nixos) is doing with their magical expression language that hardly anyone understands, could also be done with typescript, just as #pulumi does it (among other languages). You'd get universal IDE & LSP support and it's a language that everyone already loves (to hate ;)

* the documentation is shit
* the default configuration.nix that NixOS provides is "not that great"

* wiki doesn't reflect examples used other where

Another week, another "This week in #nixos" post about what piqued my interest https://blog.erethon.com/log/twin-34-2025/

#nixos could really use a naming convention for its packages.

(And why is git-lfs not included in gitFull when we're on it?)

Using nixos so far has issues at places where I didn't expect to encounter any beforehand. Like I would never have guessed that finding the equivalent of "apk search" was so difficult.

Today is **Ukrainian Flag Day **🇺🇦.

A lot of life hours could be saved by simply using --enable-languages=all and letting THAT be your GCC package. STOP the NG project, whatever it is, that surely will be rejected by GCC developers. And --enable-bootstrap by default on all native host builds! The compilers are supposed to be SELF-HOSTING. In particular the C/C++ and Ada compilers are self-hosting. The bootstrapping also double-checks that the compiler produces consistent output.

Understand GCC and work WITH it!

#NixOS

You can want GCC to be what you preconceived it to be and wrote it into your system to be all you want, but you are being presumptuous to do so. GCC has been this way a long time and has made a lot of people very happy. A goal of front-end developers has been to get accepted into GCC proper. They do not want to be part of the LLVM infrastructure nor cater to the peculiar desires of NixOS developers.

Especially if the latter do not even do properly self-hosted builds! Which they do not.

#NixOS

The enormous complication of how GCC fits into NixOS is due to a preconception by the NixOS developers that "gcc" is the GNU C compiler.

It is NOT.

The "gcc" command is the GNU compiler DISPATCHER.

The GCC package is not meant to be compiled on separate occasions to get different languages. Nor is it meant to be considered a virtual machine apart from its front ends, the way LLVM is. GCC is a single large package that some (not all) distros happen to break into parts.

#NixOS

Last week I participated in the quadrennial large Dutch hacker camp, #WHY2025. It was a blast.

It's interesting how many ways there are to experience it: I helped organize in the Info team, hung out at the #NixOS Village, gave a talk about the IT infrastructure at Museum @EICAS , went into a rabbithole debugging the Linux kernel (more on that in a separate toot), joined jamsessions, caught some talks, met many interesting folks, and much more. Serious topics (like voting systems, global politics and security) mix with more lighthearted fun (Flamethrowers, Faxe Kondi and heaps of colorful LEDs). From the 40th anniversary of @phrack to teenagers finding their own way.

I think what unites us all is the sense of curiosity and creativity.

Looking at the #NixOS installer's partitioner and disk layout options, I can only conclude this is a practical joke?

@hunderoute @Das_K

Ein Programm neu zu installieren bringt auf #NixOS garnichts. Da es ein reproduzierbares System ist, hast du danach den exakt gleichen Zustand wie vorher.

Wenn ein Programm *bei dir* nicht mehr funktioniert, kannst du die User-Daten löschen. Wenn das installierte Programm grundsätzlich nicht funktioniert, musst du eine andere Version installieren.

Da Signal nur neue Versionen erlaubt, bist du gezwungen ein Update zu machen. Wenn es das bei NixOS nicht gibt, musst du warten.

@hunderoute

Ich würde, ohne #nixos zu kennen, Signal reinstallieren.

Hallo #NixOS - Kenner*innen

NixOS mods strike again "when we want": https://discourse.nixos.org/t/did-nixos-logos-colours-changed/67866

For me, this has never been a question about changing the colours of a logo, but about accountability. As Domen said: [...] Otherwise, what stops someone from deciding tomorrow to start posting Dogecoin memes under the official NixOS branding simply because they “have the autonomy” to do so? [...]

There is a problem within the NixOS project’s moderation and marketing teams. While I still like the project very much, I find myself feeling increasingly disconnected from their views and actions with each passing day.

Dream come true yesterday!

I got to talk to a packed room of normal (non technical people) at the local library about how important it is to upcycle computers, and how Linux can save the world in this respect.

Thanks to all the people who showed up, supported, donated laptops and listened. We even gave away 9 free laptops at the event.

Library said it was the most well attended event they've had! So will be many more of these in the future. :)

XML characters are escaped for 'targets.darwin.keybindings' and 'launchd.agents.<name>'. Special characters used in strings passed to 'targets.darwin.keybindings' and 'launchd.agents.<name>' are now escaped before being included in the generated plist files. If you were doing manual escaping you will need to stop to avoid double escaping.

Ever wondered how many CI systems are involved in Nixpkgs and #nixos? Where they're configured and how they integrate with each other?

I wanted to figure this out and document it somewhat, so here's a blog post about how NixOS is built.

https://blog.erethon.com/blog/2025/07/31/how-nixos-is-built/

A new service is available: 'services.rescrobbled'. Rescrobbled is a music scrobbler daemon. It detects active media players running on D-Bus using MPRIS automatically updates "now playing" status, and scrobbles songs to Last.fm or ListenBrainz-compatible services as they play.

Well, it's official! The very first #nixbook installer is now live and completely works!

Now you can download an iso, boot to it, and install Nixbook or Nixbook Lite, reboot and you're good forever!

For those who don't know, Nixbook is basically a super easy to use #linuxmint type clone built in #nixos with automatic updates and upgrades for non technical / technical users alike!

https://github.com/mkellyxp/nixbook/

So, it turns out the nix configuration I was using doesn't play well with pkgs.php.buildEnv. While this method allows me to add extensions from nixpkgs, the bundled pecl and pear are hardcoded to the PHP without the extensions in the nix store.

Is anyone out here involved in the nix + PHP ecosystem? I have... questions. :)

I figured out how to use #agenix on #nixos

https://www.splitbrain.org/blog/2025-07/27-agenix

#blogpost

I'm just wildly pleased with the switch to #NixOS.

My Pi was super dead after the latest storm related power issues, even the external drive doesn't power up properly anymore.

So I hacked together a deploy script and repurposed the mini PC I wasn't actually using. A couple days later and now I've got #HomeAssistant back up in a container, centralized my admin and backed it up to version control.

"Maybe someday" automation items were accessible immediately. I love it.

The zsh module has been refactored to improve path handling. Previously, path resolution was inconsistent and relied on hardcoded `$HOME` references. The module has been restructured to use dedicated path handling functions that properly handle both absolute and relative paths while maintaining consistent behavior. As part of this refactoring, the use of relative paths has been deprecated. Users are encouraged to use absolute paths for more predictable path resolution.

Grrr, why does every other new #NixOS module need to use DynamicUser 😒
It is not compatible with easily providing sops secrets and using LoadCredentials is just a pain in the ass. Also it usually has negligible benefits.

I am trying to find some prior example on Google for #libretranslate, #mastodon and #NixOS and end up on my own Gitea on the implementation issue. Bruh 😂

И года не прошло, я снова на #NixOS
Старый флейк был довольно плохой, но сейчас я учёл все ошибки и переделал всё. Вдохновился ютубером Ampersand и его флейком.

А ещё из его же флейка взял поддержку нескольких хостов, поэтому я использую одинаковый конфиг и на ноуте, и на компе.

How to find config values for a #nixos system using flakes:

cd into the directory with your flake ( ex: https://github.com/shapr/whiro )
run "nix repl"
then inside the repl ":lf ." (load flake 'here')
and then:
"nixosConfigurations.whiro.config.mailserver.mailDirectory"

#Windows is such a laugh 😒

I installed #WSL #Ubuntu by accident while installing #NixOS #WSL and now I cannot get rid of it. When right clicking it and hitting Uninstall it opens the Installed apps settings section where Ubuntu is nowhere to be found.

what does the ... in { ... }: {} in nix files mean

#nix #nixos

#nixos users, if you're trying some new software that's available both in nixpkgs and flatpak, and both are kept up to date well enough, do you have a preference for which you use?

In my case running on nixos-unstable I often have to comment out packages when there are build failures, so I've been leaning more and more on flatpaks to get around that, but I'm curious how others decide between nixpkgs, flathub, appimages, or whatever else

I packaged one of my favourite childhood games, Boulder Dash for Nix. Do you guys think there's any interest to make it an official package?
It's called gdash, and it's a close-to-the-original remake!

back to the X230. The great thing about #nixos is that this 13 year old back-up laptop s pretty much in the same state as my day-to-day one. I can use it for "normal" projects but sadlly the 4 cores and 8GB of RAM are no match for the 16 cores and 64GB of RAM which I apparently need to run PHPStan on a terrble codebase.

> #NixOS is a terrible solution rather than a reproducible one. Adding a layer of complexity to simple text files that can be easily edited and having thousands of links that are links to other links is just stupid. Filling up disk space like crazy and using more machine resources on trivial tasks is not an elegant solution. Editing configuration.nix or any other module, reading all the idiotic variable definitions that were invented to change a simple variable in a text file, is boring.

I'm once again asking if anyone here knows how best to make a custom #nixos installer, that customizes the #calamaresinstaller to remove some options, and run a script post install that will patch something into the config.

I have a repo where I can build the gnome installer, but can't figure out how to customize it. I've chatgptd and googled.

Any good resources on this?

#CopterPortrait Meet Flik¹, the #multicopter we developed our first #PARASITE payload for. It's a commercial dji Mavic 3E drone typically used for photography. Here, Flik is measuring for the #TeamX campaign in #Austria, which will eventually improve #mountainWeather forecasts.

🌡️ Our PARASITE system (running ❄️ #NixOS) has several ventilated meteorological sensors on board for temperature and relative humidity.

💨 From all the data we get from copter and sensors we derive a fast 3D wind measurement. So yes: We can now measure #turbulence with a copter, without the need for an actual anemometer: The copter is our anemometer!

✅ Comparisons in #Falkenberg with a @DeutscherWetterdienst tower shows that the data quality is comparable to ultrasonic anemometers - the current gold standard of operational turbulence measurements.

#CopterPortrait Meet Flik¹, the #multicopter we developed our first #PARASITE payload for. It's a commercial dji Mavic 3E drone typically used for photography. Here, Flik is measuring for the #TeamX campaign in #Austria, which will eventually improve #mountainWeather forecasts.

🌡️ Our PARASITE system (running ❄️ #NixOS) has several ventilated meteorological sensors on board for temperature and relative humidity.

💨 From all the data we get from copter and sensors we derive a fast 3D wind measurement. So yes: We can now measure #turbulence with a copter, without the need for an actual anemometer: The copter is our anemometer!

✅ Comparisons in #Falkenberg with a @DeutscherWetterdienst tower shows that the data quality is comparable to ultrasonic anemometers - the current gold standard of operational turbulence measurements.

¹ yes, from #Pixar's #BugsLife 🐜 😉

Great news for #NixOS and nix users wanting to run bleeding edge, unreleased versions of #QGIS As of today you can now simply run this command to run the latest version of #QGIS in git:

nix run github:qgis/QGIS#qgis

Note: When you run this command, it will take a while and your CPU will work hard since it builds everything from source.

Thanks so much to @imincik for this amazing and far reaching contribution to #QGIS !

I am sitting here in #Tübingen while my colleagues @umphy are in the mountains in #Austria (#Inntal) and fly our #multicopter​s with PARASITE payload (running #NixOS) to do wind and other meteorological measurements. I can fix issues in the software (and the entire OS!) from here, over the internet. I can test my changes in a local VM here and on a spare system next to me, then deploy with one command: nixos-rebuild --target-host …

It's magical 🤩

Interesting side effects of running #NixOS with flakes:

1. I can run a `nix flake update` + rebuild, even after months of ignoring a computer. No fear of breaking everything, since I can always roll back. I used to be really bothered by `apt upgrade` on stale environments.
2. I can run daily committed upgrades (still a problem in CI, since Github actions goes out of disk space, when doing so)

Thinking of #libvirt and #xml gives me itches 😨

That's why I've been baking a simpler virtual machine manager with:

- #Vm declaration in #Toml,
- And easy #network configuration,

What do you mean, you cannot install #NixOS on your 32×100Gbps switch?

I spent literally hours trying to make https://layout-parser.readthedocs.io/en/latest/example/deep_layout_parsing/index.html work in virtualenv so that I can OCR text from newspaper article scans

Eventually, I got it to work (with lots of pinning) and thought: this will be a pain to productionize for my #NixOS server! …but ultimately I realized all packages I needed were actually already packaged in nixpkgs! 😅

Now with a flake.nix like https://gist.github.com/stapelberg/45bd82dec9d299fc1cf481c07f0c051d, I have a reproducible (stable!) way of running this program 🥳

Just tried #davpush 0.0.3 for #nextcloud that was recently packaged for #NixOS and it works with #WebPush (#Sunup)!

The #NixOS side was trivial: a one-word change. Love it.

The #DAVx5 side didn't work at all at first but it didn't even sync local changes to the server which it is independent of server-side push.

After I added another calendar and refreshed the CalDav lists, everything magically started working.

Any change I do on any side appears on the other within a few seconds. Very nice!

I upgraded to NixOS 25.11 (unstable) because I couldn’t check for an upgrade within 25.05 — Podman depended on an outdated version of Electron (34.5.8), which appears to be end-of-life.

I wasn't willing to override the configuration to allow insecure or deprecated software, nor did I want to selectively mix stable and unstable packages. So, I decided it was best to upgrade the entire system.

“fun” fact about nix flakes: Because their caching behavior is frankly atrocious, Claude Sonnet seems to have internalized that nix will just sometimes use an outdated file and cannot be trusted.

Ofc you heard that Nix is Turing complete, but how exactly make it execute a Turing machine? Here's the example:
https://stuebinm.eu/git/playground/tree/nix-turing/turingmachine.nix
From comment from top of the file:
> a turing machine in Nix. Each step will produce a new entry in the nix store containing the current band & state; it terminates by deliberatly producing a syntax error.

We're about to stop shipping VPN plugins by default with #networkmanager.

This means you'll need to explicitly configure the ones you need via `networking.networkmanager.plugins`.

In fact, if you are relying on a VPN via #NetworkManager go and do that now to prevent any interruptions.

@sandro @misterjoshua I mean the fact that you as an end user of the OS can just mess with and fix stuff like this is an absolute superpower of #NixOS. Without much hassle you can turn the innermost parts of the OS upside down as you like, for your own machine, *reproducibly*, once, and stop thinking about it, because it integrates (and stays!) directly in the roots of the OS, and sharing your work including context and timeline is as easy as a git push.

Today I've been fighting again with this absolutely stupid #NixOS bug that dates back nearly 20 years now, which prevents you from naming an executable 'log'. Yes, it is NOT possible on NixOS. 🤦 🤦 🤦 And working around it is beyond frustrating. Fixing it requires a mass rebuild, so it's not that simple. 😩 😂 It's so terrible but also hilarious...

Hey #NixOS people, do you think it's possible to make a bootable iso nix installer that will simply confirm if they want to wipe this computer and install nix, and if they type Y, it will do a completely unattended format and install of NixOS with all the settings preset?

(And obviously run nmtui or something first to connect to wifi)

IMPORTANT for #Lix users: look out for this critical bug that can bork your system: https://lix.systems/blog/2025-06-27-lix-critical-bug/

They give you other ways of fixing the issue, like patching Lix. But if you need a quick fix, you can downgrade, but that will make you susceptible to a security CVE (granted there's no known attack vector yet). If you want to downgrade but don't know how, here's a reference for Flakes: https://codeberg.org/8bitbuddhist/nix-configuration/src/commit/d5d7eebf169fc98c5fe47d578833498b77bf4ac5/flake.nix#L31
