Replace Debian install with NixOS on Scaleway

This is based on nixos-infect.

These instructions assume you have x86 scaleway machines that use UEFI and DHCP. You have may have to change /dev/vda15 if your machines are partitioned differently.

First, rsync your configuration to /root/configuration.

Run:

msteen

{ config, lib, ... }:

with lib;

{
  # Add support for Grub secrets
  config = mkIf (config.boot.loader.grub.enable && config.boot.initrd.secrets != {}) {
    boot.loader = {
      supportsInitrdSecrets = mkForce true;
      grub.extraInitrd = "/boot/grub/secrets-initrd.gz";

This is based on nixos-infect.

These instructions assume you have a machine using MBR to boot and DHCP for networking.

Run manually:

apt update
apt install curl rsync libfile-slurp-perl xz-utils

mkdir -p -m 0755 /nix
