I'm looking forward to change keyboard layout soon
Clone my repo, then add .secrets/ directory with the file .secrets/github-access-token
Make sure there is no new line in the file (0x0a)
Build the system with with
sudo nixos-rebuild switch --flake .<profile-here> --impureOr with the build.sh script
./build.sh system <profile-here>impure lets you read gihub credentials from .secrets
I don't place my config in /etc/nixos/ but I have this repo on my home inside .config/nixos
Take a look around (might not be updated to the lastest version)

You can manage the user environment without sudo thanks to home manager. Inside flake.nix there is a profile for santo@home that imports the modules at home/santo/. You can build your profile with home-manager with this command:
home-manager switch --flake flake.nix#santo@home --impureOr with my build script
./build.sh home santo@homeFor developement consistency, NixOS uses (enforces...) the use of nix-shell (or nix develop for flake configuration). You can create and enter into developement environment it with the command nix-shell. You can provide the packages with -p or use a configuration file like so:
modules/shell/shell.nix
{ pkgs ? import <nixpkgs> {} }: pkgs.mkShell {
nativeBuildInputs = with pkgs.buildPackages; [
libgcc
# cargo
# rustc
];
}See modules/shell/shell.nix for more information.
Example usage
nix-shell -p gcc
nix-shell /path/to/shell/configuration.nix
nix develop nixpkgs#gccWith nix develop you mantain in scope all your user programs
nix-shell home/shared/fhs.nixnix-shell -p appimage-run
[nix-shell]$ appimage-run <your-appimage>nix flake updateRemove system versions and packages no longer used by new generations by 15 days
nix-channel --update
sudo nix-channel --update
sudo rm /nix/var/nix/gcroots/auto/*
nix-collect-garbage -d
sudo nix-collect-garbage -d
sudo nix-store --optimizeCreate a file such as main-user.nix
Then add It into the configuration.nix file
imports = [
./hardware-configuration.nix
./main-user.nix
]In main-user.nix
{ whatever, ... }:
{
# Config here
}If you call a file default.nix, you can access It just bu importing It's folder
