• Installing NixOS on a new/existing device
• Installation inside an existing Linux system

First we need to generate the device-specific NixOS Installer with SSH and NetworkManager support. To generate the installer you can run:

nix build .#installer-iso-<hostname>

Once booted, the system can be installed running the script install-system.

WARNING: all device data will be lost.

For Debian-based systems we need to have curl, rsync, zsh, xz-utils and git-core before proceeding. Use:

sudo apt install -y curl git-core

The user must use zsh as shell so do it using:

sudo usermod -s /bin/zsh otavio

Install the daemon inside the existing operating system with:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

Finally, clone this repository as:

mkdir -p ~/src
git clone https://github.com/otavio/nix-config.git ~/src/nix-config

Add the required channels to the environment, using:

home-manager switch --flake '.#otavio@generic-x86'
