NixOS noob trying to build his system

My NixOS configuration using home-manager and flakes

Inspired by https://github.com/librephoenix/nixos-config/

Installing instructions

First steps

1. Download the minimal NixOS ISO image from https://nixos.org/download.html/nixos-iso

2. Boot into the NixOS installer

3. Run sudo -i to obtain root privileges

4. If necessary, change the keyboard layout (e.g. loadkeys de)

5. Now connect your machine with the internet

Paritioning

We are implementing following example parition layout:

Device	Size	Filesystem	Label
/dev/sda1	457G (free space left)	ext4	nixos
/dev/sda2	8G (size of your RAM)	swap	swap
/dev/sda3	512M	fat32	boot

Create new gpt partition table

parted /dev/sda -- mklabel gpt

Create new root partition

parted /dev/sda -- mkpart root ext4 512MB -8GB

Create new swap partition

parted /dev/sda -- mkpart swap linux-swap -8GB 100%

Create new boot partition

parted /dev/sda -- mkpart ESP fat32 1MB 512MB

parted /dev/sda -- set 3 esp on

Formating the new partitions

mkfs.ext4 -L nixos /dev/sda1

mkswap -L swap /dev/sda2

mkfs.fat -F 32 -n boot /dev/sda3

Mounting the new partitions

mount /dev/disk/by-label/nixos /mnt

mkdir -p /mnt/boot

mount /dev/disk/by-label/boot /mnt/boot

swapon /dev/disk/by-label/swap

Installing the NixOS configuration

Enable flakes on the live system and install git

mkdir -p ~/.config/nix/
echo experimental-features = nix-command flakes > ~/.config/nix/nix.conf
nix profile install nixpkgs#git

mkdir -p /mnt/home/user/
cd /mnt/home/user

Clone repository

git clone "https://github.com/MacKenzie779/nixos-config.git"
cd nixos-config
nano flake.nix

Generate hardware config for new system

nixos-generate-config --root /mnt --show-hardware-config > profiles/nixdesk/hardware-configuration.nix
git add .

Install base system

nixos-install --flake .#system
reboot

Login as root and set user password

passwd user

Exit as root and login as user in order to install the home-manager configuration

nix run home-manager/master --extra-experimental-features nix-command --extra-experimental-fetaures flakes -- switch --flake ./nixos-config#user
reboot
