This tutorial has not been written yet. What you see below are just rough notes.
Boot from a NixOS install live CD (“minimal” version is sufficient), and then:
# Assuming your system is x86_64-linux
sudo nix \
--extra-experimental-features 'flakes nix-command' \
run github:nix-community/disko#disko-install -- \
--flake "github:nixos-asia/website?dir=global/nixos-install-oneclick#oneclick" \
--write-efi-boot-entries \
--disk main /dev/sdadisko disk partitioning
In this second tutorial, we will walk you through the process of installing NixOS. Unlike the first installation tutorial, we will use the command line to install NixOS manually, except for using disko to specify disk partitions declaratively in Nix itself. This is the first step toward our next tutorial, where we will automate the entire installation process.
You now have a reproducible disk partitioning scheme. This does come at the cost of a few extra manual steps, but you can automate them with a script. Which is what we will do in the next tutorial. We will use nixos-anywhere to automate the steps above and eliminate the need for a USB flash drive (assuming you have a working Linux system or are booted into a rescue image).
