@jakehamilton Hi, how do you get funds for this? Do you do this out of your own free time?

I wish there was a way for me to get some funding - I want to learn and contribute to "Guile Steele", a hypothetical low-level language with powerful macros. Either that, or migrate the Nix daemon from C++ to Guile.

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

I need someone who already has an account on https://git.lix.systems/ to file a bug report for me. I have repeatedly tried to create an account and the email confirmation email just never shows up.

I would also accept "manual creation of a non-github-based account" for me (as per the FAQ). No, I can't use Matrix to ask for one. I don't want to talk about that.

(for arbitrary nixos system configuration including disko-based declarative partitioning, how to enable generating *both* test VMs and installers? the obvious answer would seem to be "nixos-generators" but `nixosGenerate { format = "vm-nogui"; ... }` ignores disko configuration inside the `...`.)

@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

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.

#Nix #nixpkgs #golang #vendoring

#OceanSprint 2025 is over, it was an great experience!

I mostly worked on gobuild.nix, a next-generation builder for Go in nixpkgs. gobuild.nix removes vendoring for Go packages in nixpkgs, modeling the full dependency graph in Nix. Each module dependency will be its own derivation, including build cache on a module level.

During the sprint, I moved gobuild.nix from linking dependency source into a vendor directory to providing a local directory that can be used as GOPROXY. This is both more versatile and simple.

Together with @britter I started implementing a code generation tool that will help to package the large number of packages that will be part of the Go dependencies package set. The tool generates the Nix code for these packages, including the FOD hashes.

Spending a chunk of my weekend wrangling servers and once again frustrated with Guix in particular for how heavyweight the package manager is. There's this one VM that only needs like 5-10G of disk space* and 1G of RAM to do its actual _job_ but if I don't provision it with twice as much RAM and four times as much disk, `guix pull` and `guix system reconfigure` are liable to run the thing completely out of storage and crash.

I have a concrete idea for what to do about this, I call it a "drone" deployment of a declaratively configured OS. In Guix terms, this would be a type of system image, in which the guix-daemon and the `guix` command are *not* included. The store would include only the packages required at runtime by the operating-system spec, not any of the packages required to rebuild them.

The idea is that you have a separate beefier machine that rebuilds the image periodically, and then you push that image to the drone somehow, ideally in a way that mimics `nixos-rebuild --boot` (i.e. the running system is not affected until you reboot it).

In addition to making it possible to use a smaller machine or VM instance with this kind of OS, this should also be good for server hardening. The store could be kept read-only, you wouldn't have to consider the package manager as part of the attack surface, etc.

Has anyone done anything even vaguely like this already? For any base OS, not just declarative distributions of Linux?

* the part of me that grew up in the days of 1.44MB floppy disks is horrified that this is a *small* amount of disk space, but that's a me issue

Features like IFD are useful in build systems because they allow build systems to be Monadic, in the words of the Hadrian paper: build things to decide what to build. By comparison, an Applicative build system such as Bazel can only take in things that are known statically; in Bazel it is thus common to check in generated build instructions. This property in category theory is illustrated in the type signatures of the operations of Monad and Applicative:

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

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

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

Made module to define GitHub/Gitea actions in #nix instead of `yaml` by rendering `nix` code to `yaml` using a defined package and/or pre-commit hook. This allows reuse of `nix` configured workflows across repositories 🚀 . Currently very much so a work-in-progress but issue reports and feature requests are very welcome so that it can be refined: https://github.com/nialov/actions.nix

Currently https://github.com/hercules-ci/flake-parts is "required" but supporting more vanilla flakes is easily done, if needed.

https://bmcgee.ie/posts/2025/02/nixos-the-power-of-vm-tests/

@jakehamilton This is part of why it's still experimental. Some of the bad decisions are not feasible to support indefinitely.

A clear benefit of doing more in "user space" is that you get to change your mind about how composition and extension work, without a backcompat nightmare or losing compatibility (and making reproducibility moot).

We're making good progress on fetching, although we did underestimate it at first.
2.27 will have Git LFS and proper submodules support.
Also a bit of locking: 2.26 had a significant fix for relative path flakes (in-repo flake inputs).
More locking, as well as composability and extension/configurability will come.

#Nix #Flakes

If I have a nix devShell defined in a nix flake with a bunch of stuff that I use locally do something, is there a way for me to take this devShell and somehow yeet it into an OCI container so I can have this environment in our CI things as well?

Been playing around with numtide's blueprint and devshell to set up a dev environment for a #Gradle application - turns out, it's pretty fun! 🎉

What started as just a simple #DevShell ended up with pre-commit hooks, a basic gradle derivation and a #NixOS module with tests.
This should be a good starting point for my next projects.

#nix and #NixOS do HaaS: Hard-coding as a Service.

You tell it what you want your system to look like and it hard-codes the sh*t out of it.

This comes with all the benefits of hard-coding: Your environment, your PATH, manually installed software, etc. don't interfere with your base system at all. Every program and service sees exactly the dependencies and configurations they were given. The amount of power this gives for servers/embedded/purpose-built machines cannot be overstated!

Hey #nix users. Is there a way to add a font in a flake.nix only for the "nix develop" or is that generally impossible as fonts are always system wide?

Oh boy is working with strings terrible in #nix 😩

I need a function that escapes a string for use as a systemd service name. Especially the asterisk * is a problem, which makes building system-units fail. But nix has no regex-replace 😩 And I can't even find how to iterate over the characters in a string to do it semi-manually...

EDIT: Using an increasing number now instead of that problematic field, but still...

Hello @lix_project !

I'm currently running Lix on my mac based on the original determinate systems installer and I was wondering:

Is there a way to switch from Determinate to Lix's own installer?

I'm using a system flake with nix-darwin and home-manager so I don't thinks it's trivial to undo what the determinate installer did (so I could do a clean lix in taller based setup)

I recently contributed a patch to erofs-utils which has now been released with v1.8.3. It introduces a --hard-dereference option that converts hardlinks to separate inodes, similar to the equally-named flag in tar. It can be used to ensure reproducible image builds on systems where similar files from the root FS might be hard-linked against each other for optimization reasons -- like in the Nix store.

After yesterday making a list of things that need doing on discourse (https://discourse.nixos.org/t/apparmor-on-nixos-roadmap/57217?u=grimmauld), i started working on #nix tooling for #apparmor

I managed to use the nixpkgs package as a basis and clean up all the cruft apparmor has accumulated in the past 13 years since it was added.
Highlights:
- ALL tests of ALL components pass!
- strictDeps is enabled
- made it all more readable and maintainable

I developed this using flakes in my fork:
https://gitlab.com/Grimmauld/apparmor/-/compare/master...nix.dev?from_project_id=4484878

I call this progress :)

We are hosting the 8th iteration of our Brussels #Nix / #NixOS / #Guix User Group Meetup next Monday, December 9th, at @HSBXL! https://brunix.glitch.me

So I just finished converting my #Nix config to Snowfall, and nothing about my system changed, which is as good of a review as I can give for a Nix framework. Shoutout to @jakehamilton for keeping it going (and for hosting your config online so I can ~~steal from~~ reference it 😛)

https://snowfall.org/guides/lib/quickstart/

did you know: you can use the experimental `nix` CLI of CppNix/Lix on non-flakes projects?

nix-build -A myAttr.foo => nix build -f . myAttr.foo
nix-shell -A myAttr.foo => nix develop -f shell.nix myAttr.foo
nix-instantiate --eval foo.nix -A myAttr.foo => nix eval -f foo.nix myAttr.foo

#nix

This is one of the most useful tools I have built:

Here, a development environment that installs

1. Bun
2. Playwright
3. Chrome, firefox and a generic webkit browser

And sets it up correctly, in an isolated environment? With a nice "hey, this is how you use this development environment" comment as a cherry on top?

The entire Nix file is 46 lines of code. Most of it boilerplate.

#nix #nixos

I love Nix so much, because you can just super easily contain an entire development environment in one file. This stuff is genuinely

- More flexible than docker
- Easier than docker
- More reliable than docker
- Faster than docker
- More powerful than docker

Why isn't literally everyone using Nix?

I have released an opinionated Nix Flake template for Deno.

https://github.com/Ookiiboy/templates

Features include:
- direnv file - for you cool kids
- Pretty good .gitignore
- Built-in git hooks; no setup required, runs deno tooling on commit.
- Linked `.editorconfig`
- Nix formatter already setup

Should be fairly turnkey.

Incremental builds in Nix and garnix

"[Garnix] approach is to make the derivations you want cached to output their cache (for instance in a separate output), and then to import a previous version of that derivation, and use the cached output from that version in the new one."

TIL: `git archive` is used by GitHub and other forges to create an archive of a repo to download. git can do unexpected thing when creating such archive, like variable substitution using the `export-subst` feature. So even if a commit is immutable, you can still download different content if a ref or tag changed.

https://git-scm.com/docs/git-archive/2.46.0#Documentation/git-archive.txt-export-subst

Example: https://github.com/smallstep/cli/blob/master/.VERSION

That's a real problem in context of reproducible builds (or just source-pinning in general).

If you're using #Nix directly from the Nix upstream: skip the 2.25.0 release, or adjust your Nix expressions. Users of https://flakehub.com/flake/determinateSystems/nix are unaffected.

#Nix 2.24.10 is currently phasing in through all Determinate distribution channels. This release improves the security of Nix when using the optional, stricter sandbox on macOS.

An upstream advisory is not yet available.

Just released nix-weather, a #rust cli-tool to check how many of your NixOS system’s build dependencies are in a binary cache.

$ nix-weather -n myhost -c /etc/config/

Found Nix Requisites in 8 seconds
Checked 2789 packages in 1 seconds
Found 2676/2789 (95.95%) in cache

This is useful to e.g. “check the weather” before going for an update. If the dependencies you want still haven’t been cached, it can be useful to know you can postpone an update to a later day when the weather is better on the cache.

Feel free to try it out from the GitHub mirror (it’s likely faster than my forgejo instance, and I’d appreciate saving the bandwidth).

babe wake up, I wrote about Helsing’s presence at Eurorust, winning their drone hackathon, and whether or not they’re just an “European Anduril” or a “good” defense company.

I also talk a bit about what this would mean for a Nix sponsorship policy, and what I think the Rust community can do.

And what’s the deal with Jon Gjengset suddenly working there?

#Nix #NixOS

Running into a nixos-rebuild problem. If I run `nixos-rebuild switch --build-host [my server]`, it builds, but I get the error "sudo: a terminal is required to read the password". Running `nixos-rebuild build` on its own does work, and it doesn't ask for a password since my user's trusted. It's just the final step of switching/booting into the build that fails becaus of sudo.

I did a bunch of searching and tried a dozen different fixes, but none of them worked. The only thing that worked was creating a nixos-rebuild wrapper script that basically splits a single remote switch/boot into two separate commands: a remote build, and then a local switch/boot. Basically it looks for a "--build-host" flag, and if it finds one, it runs `nixos-rebuild build --build-host [blah]`, then runs `nixos-rebuild switch`. Here's what it looks like: https://github.com/8bitbuddhist/nix-configuration/blob/89e9f95ba9daae8fe359022d74de1b84c3e312f7/bin/nixos-operations-script.sh#L98

I feel like there has to be a better way though. Anyone else run into this issue and find a less convoluted solution?

Nice, status update from nixbuild.net! https://blog.nixbuild.net/posts/2024-10-16-a-batch-of-nixbuild-net-updates.html
Always happy to see those smaller Nix companies thrive.

To me https://docs.nixbuild.net/remote-builds/ is still one of the best introductions to nix remote builds out there.

We are hosting the 7th iteration of our Brussels #Nix / #NixOS / #Guix User Group Meetup next Monday, September 9th, at @HSBXL!

Switched my local development for Hexo from #nix flakes to #devenv (still nix under the hood) and I'm happy with the result: https://blog.goodbyeplease.com/2024/08/21/Moving-from-nix-flakes-to-devenv/

We are hosting the 6th iteration (I forgot to toot about the previous one) of our Brussels #Nix / #NixOS / #Guix User Group Meetup next Monday, August 12th, at @HSBXL! (And yes, there will be free pizzas again! 🍕)

We do a 4th iteration of our Brussels #Nix / #NixOS User Group Meetup, Monday 10th of June, at BeCentral again! http://brunix.glitch.me/

Got my first development environment (Jekyll website) running in NixOS on my Framework laptop using devenv. That makes this my first successful dev environment in nix. :) Nice work @domenkozar!

We’re doing a 2nd iteration of our #Nix / #NixOS Meetup in #Brussels tonight at @HSBXL :)

We're bootstrapping a recurring #Nix / #NixOS meetup in #Brussels on Monday, March 11. Hope to see you there! https://brunix.glitch.me

I quietly dropped a 12-part series about #rust + #nix tonight ✨

One part will unlock each week, $10/mo sponsors get access to the whole thing on day one and can share any article with friends/colleagues, etc.

Enjoy!

Post-disaster #Introduction:

I am best known for #Scala, #Typelevel, and #http4s. I geek out over #Emacs, #Nix, and the #Indieweb. I'm probably a #Bayesian.

I live in #Indianapolis, #Indiana with a #Dachshund, #Coonhound, #TuxedoCat, and a freshwater #Aquarium or five. I offset my #Jogging with #BBQ. I coach youth #Soccer and attend North United #Methodist Church.

This is a #SelfHosted sequel after a Terraform disaster. Boosts appreciated to relocate my peeps.

#Pronouns are he/him.

Hello World.

#introduction #neuhier

I'm a consultant/developer for Embedded Systems Security.

Every now and then I contribute to #NixOS and #nixpkgs

I tried blogging a few times before, but either the service went out of business after a few posts or I ran out of time for longer posts.

Expect #Security and or #Nix orientended content from me.
Ocassional ramblings on random things, too.

Hey #nix and #nixos people!

I wrote a matrix bot for nixpkgs pull request notifications.

It‘s like the cool https//nixpk.gs/tracker.html by @qyliss, which shows you which release channels a pull request has reached.

With the bot you can subscribe and get notifications, whenever it reaches a channel instead of hammering F5 in your browser tab.

Just open a query to https://matrix.to/#/@nixpkgs-bot:maralorn.de and send "help".

Looking forward to you all stress testing it!
