ejiek's NixOS setup

This is my attempt to live with NixOS as a daily driver. Be cautious that I'm still trying to figure Nix out and fit in. There might be serious idiomatic & structural flaws.

Machine	System	Status
Desktop	NixOS	Done
Framework 13	NixOS	Done
ThinkPad x220	NixOs	WIP
SteamDeck	SteamOS + Nix	WIP
PinePhone Pro	NixOS	TBD

Roadmap

• Universal navigation for Hyprland & nvim (vim-hypr-nav)
• "Legacy" nix commands follow this flake (registry + channels)

General:

• Make repo usable by multiple machines (see Wimpy's repo)
• Make usable for non ZFS machines
• Adopt encryption or a way to store secrets separately (see agenix)
• Document the way(s) this repo is used

Updating

Using Flake means that nixpkgs are no longer controlled by nix-channel of NixOS. Instead, nixpkgs are locked to flake input. To update the system one needs to update the inputs:

nix flake update --commit-lock-file

Next step is checking, what exactly was updated:

doas nixos-rebuild build --flake '/etc/nixos#' && nvd diff /run/current-system result

The final step is to switch to the new system:

sudo nixos-rebuild switch --flake '/etc/nixos#'

Updating nix-env packages

Before deciding if a given package is going to stick with my system I prefer to use it without adding it to my config. So I add in to the nix-env. These packages are not updated with the rest of the system through flake lock mechanism. Instead, they are using nix channel configured for the root user (nixos-unstable).

First one needs to update a channel, info about available package:

sudo nix-channel --update

Then update packages themselves:

nix-env -u '*'
