Tried upgrading my server to #NixOS 25.05 but my weird network setup with bridging to my systemd-nspawn containers broke. No biggie, just rebooted to the old version so I can debug later.

Let's take a look at the NixOS 25.05 release notes. 👀

Starting on the NixOS side of things: nixos-rebuild-ng, a full rewrite of nixos-rebuild in Python, is available for testing. You can enable it by setting system.rebuild.enableNg in your configuration (to replace the old nixos-rebuild), or by adding nixos-rebuild-ng to your environment.systemPackages (for side-by-side installation). It is expected that the next major version of NixOS (25.11) will ship with nixos-rebuild-ng by default.

#NixOS

Hey! This afternoon, I'm giving two introductory workshops on #NixOS and #RustLang at @hsg, and I'll do it again next Saturday at @tdose :)

I was encouraged by the new "--flake" option that got slipped in to an update to nixos-generate-config. Maybe 30 releases from now I'll be able to make videos which don't apologize for using them.

A new module is available: `services.wayvnc` wayvnc is a VNC server for wlroots based Wayland compositors.
#NixOS #Nix #HomeManager

A new sketchybar module has been added. - Simple configuration with a single `config` option that accepts the configuration as lines, a file, or a directory. - Support for both bash and lua configuration types - `extraLuaPackages` option for additional Lua dependencies - `extraPackages` option for additional runtime dependencies - Integrated launchd service management
#NixOS #Nix #HomeManager

Next, a nixos-rebuild build-image sub-command has been added. It allows users to build platform-specific (disk) images from their NixOS configurations and works similar to the popular nix-community/nixos-generators project. See new section on image building in the NixOS manual. It is also available for nixos-rebuild-ng!

On the nixpkgs side of things, the no-broken-symlinks hook was added to catch builds containing dangling or reflexive symlinks, as these are indicative of problems with packaging. The hook can be disabled by providing dontCheckForBrokenSymlinks = true; as an argument to mkDerivation.

substituteAll and substituteAllFiles have been deprecated in favor of replaceVars and will be removed in the next release.

And I already posted about the improvements of lib.packagesFromDirectoryRecursive] being able to construct nested scopes matching the directory tree passed as input..

#NixOS #nixpkgs

Finally, a NixOS module has been added for ncps, a Nix binary cache proxy service implemented in Go using go-nix. It's available as [services.ncps](options.html#opt-services.ncps.enable).

#NixOS

To avoid delaying user logins unnecessarily the multi-user.target is no longer ordered after network-online.target. System services requiring a connection to start correctly must explicitly state so in their service configuration. Really happy to see this change, it will likely speed up boot times for many users.

#NixOS

The nixos-generate-config command now supports a optional --flake option, which will generate a flake.nix file alongside the configuration.nix and hardware-configuration.nix, providing an easy introduction into flake-based system configurations.

#NixOS

Next, a nixos-rebuild build-image sub-command has been added. It allows users to build platform-specific (disk) images from their NixOS configurations and works similar to the popular nix-community/nixos-generators project.

It definitely is nscd/nsncd.

And since "disabling this is strongly discouraged" (as per the #NixOS docs), I guess you're stuck with full-blown containers if you want to prevent DNS leaks ...

On #NixOS, is programs (using gethostbyname) running inside of network namespaces leaking DNS requests a known issue?

This happens despite the nsswitch.conf (of the namespace) having the following line:

hosts: dns [!UNAVAIL=return] files

So no accidental resolve leak.

The entries in the resolv.conf (of the namespace) simply aren't used.

My guess is that this is happening because of nscd/nsncd.

A new module is available: `programs.mergiraf` Adds git integration for mergiraf to automatically resolve merge conflicts.

Okay the fastest workaround I found for now is:

# copy system manually from server to laptop
laptop$ nix copy --from ssh://server "$(nix eval --raw --apply builtins.toString .#nixosConfigurations."$(hostname)".config.system.build.toplevel)"
# then nixos-rebuild as usual
laptop$ nixos-rebuild --flake . --use-remote-sudo switch

Has *anyone ever* gotten #nix to automatically fetch things from another of your machines instead of cache.nixos.org and/or rebuilding everything _again_ locally?

The manual¹ claims one can use --substituers ssh://yourmachine, but (of course) that doesn't work. Terrible or no error messages, that weird 'SSH stdout first line:' message, different port only settable via NIX_SSHOPTS='-p 1234', hangs indefinitely at `querying info about missing paths`...

I am pretty new to #NixOS - but while I wait for my first PR (https://github.com/NixOS/nixpkgs/pull/400046) to be reviewed, I want to use the package already.

currently I add -I nixpkgs=... to my rebuilds but it feels wrong. Especially since #nix seems to be made for flexible things like this.

Where would I start finding this out? Is it advisible to get familiar with nix lang first and THEN try stuff like this or are there good resources for 'learn as you go' - which usually works better for me.

Developing #Java with #Gradle on #NixOS and needing multiple or different specific #JDK(s) (toolchain versions) might be a tricky with NixOS, as it's not following FHS and installed JDK(s) aren't placed in standard Linux locations.

Sharing a configuration to be added/imported into `configuration.nix`, that makes multiple JDK(s) available in /opt/java, and therefore Gradle's JDK auto-detection picks them.

I really like the easy way that NixOS enables you to get rid of all cruft through one config file. Discover, kwallet and elisa are part of the Plasma metapackage. Removing them in other distros gets you the warning that you, by removing them, are actually removing Plasma. Not so in NixOS. a clean working Plasma session remains, without those unnecessary addons. Re-adding them is one simple edit away.

Yay! My recent apparmor update PR to #nixos [1] has now hit the nixos-unstable repository! This means 4.1.0 is available, with various improvements.

With that PR, i completely rewrote the #nix packaging. It now supports pkgsMusl, pkgsCross and pkgsLLVM. It has the build checks flipped on, and packaging is massively simplified.

Making all this work wasn't trivial, and some oversights were made. Those have been corrected in follow-ups, though the functionality should be available already. Do report issues with this update!

Sadly, 4.1.0 does not yet bring the needed optimizations to the alias system that are necessary to efficiently confine all of the nix store effectively. That part is still a WIP.

I also have to say: I am impressed with apparmor upstream. While doing this update, i noticed the parser check suite failing when compiling against Musl libc. Apparmor is maintained by cannonical devs, ubuntu does not use musl. Yet they were willing to listen, debug and fix these issues. While not everything has been fixed yet (this is an ongoing effort), it is nice to see upstream developers wanting to support the "weird" platforms like musl nixos.

@aires I'm already using it! Although not because it's made in rust, purely because I found some Nix tooling really doesn't accommodate doas 🙄

I can't remember them all, but I know deploy-rs was the one that "pushed me over the edge", as it would only work with sudo, so I went with the more minimal sudo-rs implementation.

That said, what I've seen mentioned elsewhere which I'm really interested in, is run0

https://mastodon.social/@pid_eins/112353324518585654

Although it doesn't seem to work on NixOS, unless anyone's aware of any workarounds? This is the most recent (Nix oriented) post I've seen.

https://discourse.nixos.org/t/run0-not-working-right/62772

#NixOS #Systemd #Security

I saw a post that Ubuntu 25.10 is switching to sudo-rs, which is a rust-based alternative to regular sudo. So I decided to do the same for my #NixOS install. All it took was:

```
security.sudo-rs = {
enable = true;
execWheelOnly = true;
wheelNeedsPassword = true;
};
```

Great fun I just had with Nixbook, a project by Mike @codemonkeymike , turning your computer in a Nix-powered Chromebook. Restarted 8 years ago with Linux Mint and have been on a great Linux journey since. and yes, I've done them all (except LFS and some other curiosa). Nice to be on Cinnamon again. Did Nix as well, and still had those configuration.nix files lying around. Don't really need them, all just works. Only switched a channel of course ;-) Check it out, it's a great one!

I am very surprised that sequoia-chameleon-gnupg seems to work very well as a drop-in replacement. You still need gpg-agent and gpgconf from gnupg but using it with git and sops just worked.

And even if it didn't, with #NixOS it is easy to undo the change again.

`services.espanso` now supports wayland. This is enabled by default on Linux as `services.espanso.waylandSupport = true;`. Depending on your graphical session type, you may disable one of `services.espanso.x11Support` and `services.espanso.waylandSupport` to reduce the closure size of espanso on your system. Both x11 and wayland versions come enabled by default on Linux.

Damn. I love #nix and #nixos but NixOS updates are just annoying. They're painfully slow and lag the whole system even on high-end machines.

I got #nixos running sway entirely without libX11 in the closure!

It seems the VM rendering pipeline really does not like this, so i had to resort to display out via VNC, but good enough. Red and Blue color channels are switched - this is an issue with wlvncc on my host, and i honestly have no clue what is wrong with *that*.

If you want to look at the config, be *very scared* of cursed overlay stacks. But it does work, and is only ~150 rebuilds missing from cache!

They're all 8th gen i7 with 16gigs of ram. Def a few years old, but completely capable of daily use, esp for basic users.

People can use these themselves or give them to friends / family or anyone local to them that need a computer.

You don't have to chase the commercial endeavor, but it may come [...] to you. [...] So I would think of it this way: If you want there to be peace in the project, give people extension points where necessary, so that everything doesn't have to flow into core in order to feel like it's a first class citizen. - @kelseyhightower at PlanetNix 2025

Quite some interesting takes by Kelsey on the Nix project. I hope we can get to a point where commercial and non-commercial interests can co-exist in the project. Watch the full thing here:

In #NixOS the snow theme was used to illustrate that each flake is a perfect recreation, which didn't aptly describe this glorified build system.

The best analogy (even within the #NixOS community) has been the cooking analogy.

#Nix are the kitchen utensils, #Nixpkgs the recipes, #NixStore the pantry, packages ingredients, profiles are tables and derivations are dishes.

After some experimentation I think I have a working unprivileged #nixos container running a multi-user environment with services. In my case replacing an LXC instance.

nixos-containers.nix needs some --bind patching with :idmap

Added extraFlags to container with private-users/chown, allowedDevices with rwm /dev/net/tun

Logrotate breaks but can be fixed with a couple of lines.

root-login to the container to set a password will leave /etc/.pwd.lock as nobody. Delete it.

Work in progress.

Dear Lazy web...

With the old #NixOS aarch64 build host dead and my request for access to the new one unsuccessful, I'm pondering the best path to having an aarch64 build machine again. I see three paths, in no particular order:

* Pay for an #aarch64 VPS and set it up as a build machine
* Re-build one of my Pi3's as a build machine
* Use cross compilation

None of them are ideal and there may be better ways.

Interested in your thoughts or other ideas.

There is also a nice article by nixcademy that gives more background on laziness, has some illustrations and more examples for fix and overlays: https://nixcademy.com/posts/what-you-need-to-know-about-laziness/

🚨WARNING🚨

Apparently some #Nix / #NixOS matrix room(s) have gotten csam spam. I have not verified this claim myself, but honestly, we can all probably just not check matrix for a few days until hopefully things are back to normal.

I do *not* know what utilities #Matrix provides to prevent the proliferation of this information. If you joined the room from a different home server then your server may have synchronized the material to your infrastructure.

I think the safest course of action is not opening a matrix client for a few days...

I continue to be incredibly frustrated with how difficult it is to fabricate a test virtual machine from an arbitrary #NixOS configuration and have that test virtual machine actually match the real thing on basic details like the (virtualized) disk layout and filesystem mounts.

Maybe I'm doing something weird here, but basically all the tests I want to do before pulling the trigger on a real installation are invalidated by this semantic gap!

I really wish whoever runs nixos.wiki would shut it down and just setup a redirect to wiki.nixos.org instead #nixos

I’ve officially deployed a Nixos based slideshow/ info screen for a client. It runs a rust client for the Xibo open source backend. It turns itself on and powers off at the end of the day. Has different systemd timers for different office hours throughout the week. Shows the weather, a slideshow of upcoming events and calendar showing that day’s events. Very slick and highly configurable. So far it’s been solid and I’m impressed. #nixos

@korenchkin Is nixos.wiki managed by non-NixOS or NixOS-hostile personnel?

Cause I tell ya, letting that link above just exist, with not so much as a "HEY DON'T READ THIS GO TO THE ONE AT NIXOS.ORG YOU NUMPTY" or something like that is pretty newbie-hostile.

Not just bad or clumsy management, but actively hostile. I dunno how much of my time that site just wasted, or how much it will waste before it is eradicated from the earth.

Oh how I do love the docs at #NixOS.

I am attempting to do the "System wide vim/nvim configuration" example at https://nixos.wiki/wiki/Vim and rebuild is giving me this error:

error: attempt to call something which is not a function but a set

I read on one forum that removing the { } you see there, the set in question, from the override line, that would fix it, but then I of course get

error: expected a set but found a function

Since this is coming straight from the wiki and my syntax is correct, this is what you might call

small Nix tool I wrote tonight: nix-binary-cache-gc

Essentially it's a garbage collector for static binary caches (i.e. directories that statically contain .narinfo and .nar files and that are served by a regular webserver). It's dependency-aware, and uses the #tvix / #snix crates.

(Previously I just deleted all files older than a certain amount of days with find and rm, but that tore up the dependency graphs on the cache and regularly caused errors)

The new NixCon organizers: "we will theme NixCon around “bridge-building”, to emphasize the importance of fostering connections [...] what better place to build bridges than Switzerland, where neutrality is so valued"

Nice, lib.packagesFromDirectoryRecursive now supports nested scopes!

packagesFromDirectoryRecursive transforms a directory tree of packages into a nested attribute set of derivations. You can use it to manage a package set in a similar way to by-name in nixpkgs (without the sharding part). The package files in tree must be suitable for callPackage.

Subdirectories in the tree result in nested attribute sets. In the following example, packages d, e and f will be in a nested attribute set called my-namespace.

my-packages
├── a.nix
├── b.nix
├── c
│  ├── my-extra-feature.patch
│  ├── package.nix
│  └── support-definitions.nix
└── my-namespace
   ├── d.nix
   ├── e.nix
   └── f
      └── package.nix

Previously, this would only use one scope (my-packages), so e could only depend on d as my-packages.d. With the introduction of nested scopes, e can refer to d within the same scope directly.

You *should* be very careful which #Nix substituters (caches) you trust since you have to trust who can push to them. Effectively you are trusting them with root on your machine.

You *should* be wary of “community” caches if you don’t want to have to vet who has access there.

You *should* build things from source yourself if you do not wish to trust the #NixOS build farm and Hydra infrastructure (or to lessen the load on their CDN)

What you should ABSOLUTELY NOT do is trust some random VC backed company (which may or may not have a business relationship with military-industrial-complex contractors) over the actual NixOS project which stewards the actual sources you trust to be secure in the first place

@eliasp While I know what you mean, I strongly disagree with that truncation.

First, the nixos hardware module needs to exist & support all of your particular hardware. This isn't a given thing depending on the HW you are about to use.

Secondly, there are still too many settings you need to do manually such as xfce environments, lots of app settings, ...

I started with NixOS in the naïve assumption that it is allowing me to define everything across all of my computers. I failed miserably & with the next opportunity, I'll switch back to Debian.

However, if you're totally open to let the #NixOS community to choose the hardware platform (devices that do have a HW config module which supports all features), desktop environment (sway?) and all apps for you, then you're probably fine with "everything in your #Nix configuration". If not, you do spread misleading vibes here - so to say.

And yes, there's still the issue with not being to run #Python in a normal way.

HTH

The amount of work it takes to migrate #NixOS to a new device is just too much! 😁

I though it had been a while without any #NixOS drama, but of course the universe provides.

Guess what, telemetry in #devenv is coming back. Again, it's Opt-Out, not Opt-In.
The difference: this time that work is sponsored by the NixOS Foundation.

Who needs pigs to fly? I think that the end times will be marked by an occasion where two #NixOS or #nixpkgs users agree on the correct way to build a FOSS project.

"use devshell"
"use flake"
"use this other flake thing"
"just use upstream nixpkgs"
"upstream nixpkgs is slow, let's use this fhsENV thing"
"use flakeutils, it's really handy"
"flakeutils that everyone uses is a waste of time, just use nix directly"
"nix2 solved all of our problems, flakes just add unnecessary complexity"
"structure the flake like this"

@luj Thinking of it, what makes #NixOS "resilient" against attacks on core packages is that the update will cause massive rebuilds, so it will probably be stuck in staging for a month or two. This happens with security fixes as well, so ... taking the bad with the bad I guess

@luj Wow, that's a long shot.

> While there is no policy about this, there is a culture among NixOS maintainers of using the source archive automatically generated by GitHub

That happend to xz not four weeks before the version in question was release. The fact that #NixOS was not affected was pure luck and had nothing to do with culture.

I have to agree with @thelinuxEXP about Firefox. We've given them a pass too often. So today I've replaced Firefox 🦊 with Librewolf 🐺

Luckily I manage my configuration and extension with Nix Home manager, so I just had to change a single line in order to make Librewolf my default browser with the same extensions and plugins applied 😎

🌊💻 OceanSprint 2025 – Day 2! 🚀

We're hacking on exciting projects like NixOS config diffing, Tvix/Snix, interpreterless initrd, and better Go support in nixpkgs. But it's not all code—we're also enjoying BBQ, mountain biking, hiking, and surfing in beautiful Lanzarote!

Great code, great people, and great vibes. Can't wait to see what we build next!

#TIL #systemd can somehow restart itself in a running system and #NixOS does it automatically whenever necessary.

This must have happened dozens of times already and I never noticed because it's entirely seamless.

I only found out because I was curious what exactly the #NixOS activation script means when it says "restarting systemd" as that struck me as near impossible.

I confirmed that /proc/1/exe points at the same store path that my new version of systemctl comes from; how cool is that?

Do you guys think i could install #NixOS on that router instead? It only has like ~100MiB of Memory tho.

yayy my "make systemd-ssh-generator work"-PR got merged
#nixos

This week i had a lot of fun! I finally decided to take the leap and open some pull requests against #nixos staging branch.

The project? Replacing SDL1 -> SDL_compat. I worked on dropping SDL from various places that caused mass rebuilds. I had help from a couple awesome people like K900, marcin and emily. Working on this was an absolute joy!

Other distros did this switch significantly earlier already. So this was definitely not something original. But to date this is probably the largest change set i contributed to nixpkgs, and i am happy with it.

Now, after the merge, there will be the fixing phase. I do expect some very few packages now fail to build or display a black screen. But all of these will be trivially fixable, in the worst case by switching them back to specifically use SDL1.

Final PR: https://github.com/NixOS/nixpkgs/pull/389106

"This is how we should have done computer science forever."

In a world where the internet is dominated by Big Data giants, NixOS is redefining how we think about infrastructure—making it more accessible, maintainable, and user-driven. You shouldn’t need to be a DevOps guru or a CS expert to take control of your system.

In the @NGIZero podcast @luj and @kms dive into how #NixOS is challenging the status quo and why a more open, reproducible approach to computing matters.

A new module is available: 'programs.zsh.initContent'. initContent option allows you to set the content of the zshrc file, you can use `lib.mkOrder` to specify the order of the content you want to insert.
#NixOS #Nix #HomeManager

uh so my todo list for what my new homelab setup needs is completely empty now!
i'll probably still find some thing to add, but i guess i'll spend the next days testing it for real and writing a guide for myself on how to migrate from my old setup to the new one and import all data.
i'm quite excited to finally see this project that i had planned for like 2 years become reality in the past 6 months or so 🎉
without #nixos i would have never been able to create this setup and feel confident that it actually all works like i want it to!!

Something useful I learned today I thought I would share with any fellow nix users hosting repositories on @Codeberg

You can specify a repository URL prepended with "git+" to run an application with the apps or packages flake output attributes:

```
nix run git+https://codeberg.org/tdback/apod
```

This should also work for any git repo available over http (although I haven't tested it yet with my cgit instance).

As a side note, it looks like some work has been done to add official Gitea/Forgejo flake inputs to nix, but the issue has been inactive for some time: https://github.com/NixOS/nix/issues/11135

#TIL about the `namei` tool which is sort of like #traceroute but for filesystem traversal.

This is especially useful on #nixos where you're frequently dealing with stuff that is multiple levels of symlinks deep.

It's probably already on your system because it's part of #utillinux; go try it out:

namei `which ls`

#namei #symlink #linux

The DetSys duality:

- Look at how cool and in touch with the Nix community we are, one of our cofounders is the creator of Nix! (don't look too closely at when we were actually founded and when eelco joined our company though)

- Oh no we definitely don't hold any control over the CppNix project and all of eelco's work on CppNix is voluntary and not paid for by DetSys, it's on his own time, we don't influence this.

(Depending of course on who they speak to and when.)

Honestly, consider switching back from #NixOS to good old #Arch after almost 1y. Nix is so unique and different and has quite a steep learning curve. And I have not enough time for that. On the other hand, I was always happy with Arch and installation has become so easy with the archinstall script.

Had a quick look on Manjaro or EndeavourOS ... but vanilla Arch it will be.

Ma recherche de DevOps n'a pas été concluante. Autant des sujets tagués #dev français on en trouve mais pour  #devops tout est en anglais, j'ai cependant pas pris la peine de vérifier si il indiquait leur lieu de résidence dans leur profil mastodon.

Y aurait-il un mot clé pour DevOps en français ?

Comment en trouver ?

Looking at ALSA on NixOS, I don't think that should actually work, because none of the config files are in a location that alsa-lib expects them to be? They are all in the nix store and I can't see any reasons in the derivation that this was patched to deal with that? https://github.com/NixOS/nixpkgs/blob/nixos-24.11/pkgs/by-name/al/alsa-lib/package.nix#L39

Or how is alsa supposed to pick up things like the use case manager config for my device on NixOS?

This is a serious proposal, we should actually ban and denounce determinate systems now.

Hey #Nix #NixOS people. I am once again making a thesis that Nix docs are not "bad", their discoverability is bad.

I've summarized my observations in a comment on an existing (yet pretty stale) issue on GitHub https://github.com/NixOS/nixos-homepage/issues/705#issuecomment-2708928266

How do we get this to reach "the right people" and start making some moves to improve discoverability? Boosts and advice appreciated.

It there's one thing I know, it's that #linux #distributions that are community driven turn out to be the most reliable. My current go to for regular users is #Fedora, because it is a solid distribution that's cutting edge and it's designed by the community.

I can't say the same for #NixOS. The amount of internal fragmentation and in fighting is too damned high, and there is possible conflict of interest that sits like an elephant in the room.

So I'm thinking... I might make a switch soon.

#Nixos ​​ and #Hyprland creatures... please i need your help ​​

So whenever I launch pavucontrol it just opens a window but it does not render anything nor do I get any warnings in the console.....

My config is here: https://codeberg.org/oricat/nix-workstation

I wouldn't be nearly as willing to experiment with software or self-host different services if it wasn't for #NixOS. It feels liberating to do basically whatever I want with my computers without the overbearing worry of irreversibly breaking something, or getting my PC into an unrecoverable state. #Nix is great tech and I really want to see it and similar tools/ecosystems thrive

I’ll be speaking at Cloud Native Days LA in #SCaLE22x about leveraging #nix / #nixos to build pretty small container images. I’ll make an attempt at showing you the benefits of using something like Nix to do this, and daydream about possible future integrations. Looking forward to seeing you there!

Day 2 of #SCALE22x and finally see the blue skies!!

If you're here today, come check out my #nixos talk at 10:30am!

Building a Chromebook replacement with NixOS

Want to help out Nixpkgs but don't know what to do? I compiled a list of still failing packages due to switching to GCC-14 in stdenv a while back. GCC changed some warning to errors in this version and lots of especially older projects fail to build now.

Plenty of examples of the fix already in Nixpkgs, ideal for first time contributors.
