mynixos.com also lets you navigate nixpkgs.

Unfortunately, nothing is standard. So I would say, across all the configs you looked at, which had a file and module structure that you understood? I’d follow that then.

My config has a users and hosts dir, to distinguish home manager and nixos configs. Inside each is the list of users and hosts configuration files. In addition, there is a modules folder that holds modules that are common among different users/hosts.

I think this is good idea. If the modules/options you are writing are for internal use, and not expected to be shared with the wider community, then this is great. I should incorporate this in my own config, but I dont know if this is common practice.

Yes. Oci-containers is similar to how you would setup a docker compose. Its not quite one to one. In particular, networks are odd, since you have to hand write a systemd service to create it? But thats only if you want isolated networks. You can find some examples on my github, I use it for most of my services. Heres an example of nocodb with backing postgres database. Its pretty simple: https://github.com/rutrum/dots/blob/master/hosts/modules/nocodb.nix let me know if you have questions in the future

That looks like the same idea for a different set of tools. That’s a great reference, thank you!

Pff, if pandas gets me numpy that works that may not be a bad hack. I’ll try this! Sorry I dont know how to fix qt!

I’ve had the same problem running numpy. Shockingly with a library so popular I havent found a way to make an environment with it work. I also had the most success with poetry, so I think you’re on the right track.

If you enable iptables you may have to disable firewall.

I am also using nixvim. Didn’t know about this fork. I think I like it? It beats manually writing setup configs. But Im not a vim superuser by any means, so I’m sure nixneovim would be equally useful to me.

Sorry about your troubles. Keep at it, I promise its greener on the other side.

One tip: nix-env installs things ad hoc. Its against fhe whole philosphy of nix, where your system state is defined in files. So don’t ever use that. If you need any generic package, you can add it to environment.systemPackages. If you accidentally installed something that way, its okay. Just know you might get an error if you try installing it both from nixos-rebuild and nix-env. If that happens, just uninstall from nix-env.

You want to look at the registry. Run nix registry list. You’ll see that nixpkgs by default points to unstable. You override this in your config. I’ve done that, where nixpkgs is stable and “unstable” is unstable.

EDIT: heres part of my home manager config that changes this: https://github.com/rutrum/dots/blob/master/users/modules/cli/nix.nix#L15

I think this has to do with flakes. If you run something as a flake it doesnt use channels, which is the alternative. The import is looking for it as a channel on the host machine. With flakes its provided as an input.

It looks like nixinfo is explicitly looking for channels to tell you info, like how neofetch would tell you interesting stats. The same does not apply with flakes. There’s no “default” upstream package base that can queried by the system.

If you want to switch slowly, I would install nix and home manager on your Arch system, and slowly migrate your dotfiles, configuration, and packages into home manager. That will give you a comfortable transition opportunity to learn nix. Then, the last 10% of system configuration you can figure out when you install NixOS, and you can just pull in your home manager config for all your userspace dotfiles and programs. Thats how I moved from Ubuntu to NixOS.

And yes, you can have home manager just symlink existing config files to the appropriate location. You don’t have to rewrite everything in nix.

How do you use your computer? Did you really just blow away your OS and jump to one you just heard about? I ask because I spend many months preparing to make the move, and I’m still working at a deficit, since my 4 year old OS had so many hours of tinkering that went undocumented and forgotten. Im still slowly configuring my nixos box. How did you use your computer?
