NixOS

I had the (perhaps foolishly ambitious) idea of creating a rolling fork of Lemmy with the intent of modifying the codebase for use in an open source pub sub implementation of retail inventory. But I have to get standard Lemmy working first...and I like to use Nix for everything I do in the dev world (where feasible).

So, I forked the repo and was immediately brought into dev environment hell.

They only offer a choice between:

A.) Docker B.) Ansible C.) Building from scratch.

Two hours of fighting with the scratch build instructions and I eventually had to admit defeat due to some vague dependencies (and general malaise). Though I have completely flakified my Purescript and Haskell dev environments, I have found Rust to be a lot more challenging even on simple projects.

Anyway, I decided to come here to ask: **How easy would it be to flakify the Lemmy repo to add a fourth build option for those of us in the Nix world? **

Can I reference the build instructions from nixpkgs to get close to my intended goal? I need all of the help I can get. Be as pedantic or defeatist as you will. I currently have no skin in this game and merely want to help the Lemmy devs welcome people that are more nixy like myself (if nothing else).

I setup a next.js project with pkgs.mkshell, and used nix develop to automatically build the project. However, when I leave the shell, the files persist. How should/can(?) I setup my shell.nix so that files in the directory it drops down into are automatically removed when leaving the ephemeral shell?

Hey guys, I'm pretty new to Nix and NixOS and one of the reasons I installed it is because I know there's some way to install the KDE 6 Beta before the official stable release. I wanted to use the kde2nix overlay, but appearantely KDE 6 has been merged into the official nixpkgs repository. How do I switch from Plasma 5 to 6? I'm already on the unstable channel if that matters.

Thanks in advance.

So I've been looking into Nix and it seems like a pretty cool way of managing machines. However, I'm curious about how well it can manage user authentication. Theoretically one should be able to setup the equivalent of roaming profiles with rsync and some sort of authentication server but I haven't seen a lot of information on this topic.

Anyone used Nix in a group or company setting? If so, how did it work?

Plenty of nix'd config, nix-colors theming for most applications. I've only been using linux for around 6 months, NixOS has really clicked with me.

My config might be sub-optimal in areas, but its gone through some heavy changes since its inception.

I've probably parsed dozens of pages now, including the "Dual boot NixOS and Windows" page on nixos.wiki, and not really sure what the best steps are since most seem to leverage the fact that everything is on a single partition. My windows lives on a physically separate drive than NixOS, so osprober does not detect the windows partition at all. I tried to go down the route of grub-mkconfig but that doesn't seem to be a nix package and I couldn't mount my Windows bootloader as it is NTFS. Is this even possible with this configuration?

My next step was going to be to physically disconnect each of my disks/NVME, nuke everything bit by bit, then only connect the disks I want and install each OS with it's specific disk connected.

I want to use Plasma-manager in my system. I have enabled flakes in configurations. Now what to do to use it. The output generated by tool rc2nix can be copied through terminal but when i put that in home.nix , it says that plasma is not available which is true but then how do I use this tool. flake file.

I've made a fun little project inspired by this (except it's not updated any more).

It provides easy instructions for installing old versions of packages, it takes them straight from the official nixpkgs repo.

Example: https://history.nix-packages.com/package/dotnet-sdk_3/3.1.426 (.NET SDK 3.1 actually prompted the creation of this tool, I needed it for one old project).

Each detail page provides instructions on how to install the package using nix-shell, nix-shell with shell.nix file, configuration.nix and nix-env.

The design is based on https://search.nixos.org/ (because I suck at graphical design).

Do let me know what you think!

I was trying to use a flake with nix-pkg to set up a flutter dev environment but it just wouldn't stick, and a lot of the examples online are quite old and not documented well for a nix noob like myself.

Cheers folks!

My server is currently running fedora and it has a encrypted raid attatched. Now i wanna move my server to nixos but i cant find anything on how to automount it. Any advice ? Thanks for your time and have a nice day!

Used nix last year but dropped it after home-manager decided to unlink the apps from the Applications directory.

How is the current situation on usability of nix-Darwin + home-manager + brew?

Packages still fails to get indexed correctly in spotlight? I really like a fully repro environment but the fact that the usu ability was low bothered me a lot.

I recently wanted to try out (aider)[https://aider.chat/], and ran into a problem that I continually run into: how do I install one-off, experimental software into my environment, without being a nix master, or spending an extreme amount of time on every new package.

In this case, it is a new python package available in pip. It isn't available in nixpkgs, and isn't nixified. pip2nix doesn't work on arm64 Macs (bug here)[https://github.com/nix-community/pip2nix/issues/88], so I can't use that to try and create a flake that works with this package. It isn't using poetry, so poetry2nix is out.

How are you dealing with this problem? Are you all experts in nix, and writing flakes for every piece of software that you want to play around with? Do you have a "dirty" part of your environment that you install this kind of stuff into? (I looked into using pipx to install this, however that (also has a bug)[https://github.com/NixOS/nixpkgs/issues/171429] in nixpkgs.)

Thoughts?

Hi there! I'm trying to make php and composer work. I have this in environment.systemPackages:

    (pkgs.php82.buildEnv {
      extensions = ({ enabled, all }: enabled ++ (with all; [
        xdebug
        redis
      ]));
      extraConfig = ''
        memory_limit=2G
        xdebug.mode=debug
      '';
    })
    php82Extensions.redis

The problem is that while running php -m correctly prints that redis extension is installed, composer does not, because it uses a different php:

• file $(which php) prints the path /nix/store/igx8j4qjxy9jyj8kjyccwarnzqq5vsml-php-with-extensions-8.2.9/bin/php
• cat $(which composer) shows that it's a wrapper for '/nix/store/lv4prxa52zifr54ws56iz3b9kdhs1b5w-php-with-extensions-8.2.9/bin/php' --add-flags '/nix/store/avqj0662f4gg2s875zlbbjajx6fm6bl0-php-composer-2.5.5/libexec/composer/composer.phar'

Note that the path to php is different. Is there any way to correct it on my side? I'd like to avoid having to install composer manually

Interesting idea.

tl;dr image buildable with some patches

South California Linux Expo is looking for papers.

I recently followed https://www.arthurkoziel.com/installing-nixos-on-a-macbookpro/ to install NixOS on a macbookpro5,1 (from 2008). OSX hasn't supported that hardware since El Capitan and it was incredibly slow even then.

With Nix it works, but I'm frequently running into issues similar to https://askubuntu.com/questions/1114612/rcu-sched-self-detected-stall-on-cpu-watchdog-bug-soft-lockup-cpu3-stuck. The first 3 times I tried logging in after the install it hung after accepting the password. It was just logging the rcu stall error every few seconds, not responding to any keys. I was able to create a user account on the 4th boot, but still haven't installed anything extra on it.

It's also really slow to boot. A few minutes in stage 1 before it asks me for the decryption password and then another few minutes to get to the login prompt.

All of this is without any graphical environment. I was planning to go with a low resource desktop like xfce or cinnamon (are they still maintained?), but any tips on what to look at before I possibly introduce more instability?
