Minimal NixOs Commands

Edit: this was done long ago, it might be outdated/unecessary now Commands to run on startup to install nixos and add the configuration

nix-env -i git
git clone https://github.com/benkio/nix-config.git
cd nix-config/

sudo su

# MBR
parted /dev/sda -- mklabel msdos
parted /dev/sda -- mkpart primary 1MiB -8GiB
parted /dev/sda -- mkpart primary linux-swap -8GiB 100%

# UEFI
parted /dev/sda -- mklabel gpt
parted /dev/sda -- mkpart primary 512MiB -8GiB
parted /dev/sda -- mkpart primary linux-swap -8GiB 100%
parted /dev/sda -- mkpart ESP fat32 1MiB 512MiB
parted /dev/sda -- set 3 esp on

mkfs.ext4 -L nixos /dev/sda1
mkswap -L swap /dev/sda2
swapon /dev/sda2
mkfs.fat -F 32 -n boot /dev/sda3        # (for UEFI systems only)
mount /dev/disk/by-label/nixos /mnt
mkdir -p /mnt/boot                      # (for UEFI systems only)
mount /dev/disk/by-label/boot /mnt/boot # (for UEFI systems only)
nixos-generate-config --root /mnt
cp configuration.nix /mnt/etc/nixos/
nixos-install
reboot

remember the root password remove the nixos image from the drive

Home Manager Installation

nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
nix-channel --update

nix-shell '<home-manager>' -A install
# mkdir ~/.config/nixpkgs
git clone https://github.com/benkio/nix-config.git
cd nix-config/
# Change it to NixOs home file if in NixOs
ln -s ~/nix-config/MacOs/home/home.nix ~/.config/home-manager/home.nix
home-manager switch

Symbolic link for NixOs Configuration

sudo ln -s ~/nix-config/NixOs/system/configuration.nix /etc/nixos/configuration.nix

MacOs - Darwin-nix

For installation of darwin-nix you can follow the instructions in this gist: darwin-nix setup and install Homebrew

Just add the symlink for the darwin configuration as follow

ln -s ~/nix-config/MacOs/system/darwin-configuration.nix ~/.nixpkgs/darwin-configuration.nix
darwin-rebuild switch
