impermanence VS nix-config

I would not call these projects unbelievable, but they are neat.

- Opt-in state: https://github.com/nix-community/impermanence and https://grahamc.com/blog/erase-your-darlings/

That way will work - I use the impermanence module which works similarly but allows to hide mounts.

This is indeed a blind spot. Thanks for pointing that out! Silverblue -to my knowledge- doesn't do a lot to address this. Though, 3rd-party tools like Home Manager and the suite of applications developed by the folks over at uBlue might be able to limit this to a minimum. Though I'm not sure if it surpasses NixOS in this regard; for the uninitiated. Though, to my knowledge, this requires special attention and depends on the specifics of the NixOS system in question.

I have recently stumbled upon Impermanence - modules to help you handle persistent state on systems with ephemeral root storage, and the concept seems quite nice.

I haven't used it yet but nix-community/impermanence has a home-manager module that might be useful.

Some files in /etc (like saved networks) will still not be managed by NixOS, if you want to have full control over them use Impermanence

{ imports = [ (modulesPath + "/installer/scan/not-detected.nix") "${builtins.fetchGit { url = "https://github.com/NixOS/nixos-hardware.git"; }}/system76" "${builtins.fetchGit { url = "https://github.com/nix-community/impermanence.git"; }}/nixos.nix" ];

There is a maintained collection of modules for running this kind of NixOS setup. It's called impermanence.

Power user, gvolpe has a great config that heavily customizes nvim.

I forked and customized a fairly advanced Nixos configuration that I can load from a flake on github. (Mine | Original)

I think gvolpe's nix-config repo is what u/ppen9u1n was referencing. Looks like there might be some good ideas to mine there.

I've seen this done with flakes by a NixOS power user named gvolpe. He has it configured to automatically setup each of his different systems with Home Manager, a custom UI, etc. His three different build targets are:

I think NixOS would benefit from easily accessible collection of opinionated modules/profiles/configurations with minimal set of options. Something like gnome-desktop / sway-desktop / etc. Gnome actually does pretty good job here.

The point is: currently my NixOS and Home Manager configurations have over 2k LOC total. When you search for configurations on GitHub/Google you are likely to find complex ones. For example, quick search for "nixos gnome" (Google) gives me link to NixOS Wiki (which describes only Gnome part) and blog post (https://gvolpe.com/blog/gnome3-on-nixos/) which is useful but links to really huge configuration (https://github.com/gvolpe/nix-config) that is overwhelming to any beginner.

Great example of such approach is nixos-hardware (https://github.com/NixOS/nixos-hardware) which provides one-line configuration covering hardware quirks.
