This script - is a modded version of original [nixos-infect](https://github.com/elitak/nixos-infect). It have been revritten to suit needs of SelfPrivacy project. Except transforming your Ubuntu Linux system into NixOS GNU/Linux, it deploys standart services that SelfPrivacy offers to their customers. ## Source Distros This script has been tested and can install NixOS from the following source distros: On Digital Ocean: - Ubuntu 20.04 x64 On Hetzner cloud: - Ubuntu 20.04 On Scaleway cloud: - Ubuntu 20.04 ## Considerations nixos-infect is so named because of the high likelihood of rendering a system inoperable. Use with caution and preferably only on newly-provisioned systems. *WARNING NB*: This script wipes out the targeted host's root filesystem when it runs to completion. Any errors halt execution. It's advised to run with `bash -x` to help debug, as often a failed run leaves the system in an inconsistent state, requiring a rebuild (in DigitalOcean panel: Droplet Settings -> "Destroy" -> "Rebuild from original"). ## Digital Ocean *TO USE:* - Add any custom config you want (see notes below) - Deploy the droplet indicated at the top of the file, enable ipv6, add your ssh key - `cat customConfig.optional nixos-infect | ssh root@targethost` Alternatively, you may utilize Digital Ocean's "user data" mechanism (found in the Web UI or HTTP API), and supply to it the following example yaml stanzas: ```yaml #cloud-config runcmd: - curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | PROVIDER=digitalocean NIX_CHANNEL=nixos-20.03 bash 2>&1 | tee /tmp/infect.log ``` Potential tweaks: - `/etc/nixos/{,hardware-}configuration.nix`: rudimentary mostly static config - `/etc/nixos/networking.nix`, networking settings determined at runtime tweak if no ipv6, different number of adapters, etc. ```yaml #cloud-config write_files: - path: /etc/nixos/host.nix permissions: '0644' content: | {pkgs, ...}: { environment.systemPackages = with pkgs; [ vim ]; } runcmd: - curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | PROVIDER=digitalocean NIXOS_IMPORT=./host.nix NIX_CHANNEL=nixos-20.03 bash 2>&1 | tee /tmp/infect.log ``` ## Hetzner cloud Hetzner cloud works out of the box. When creating a server provide the following script as "User data" (this has been tested using Ubuntu 20.04 as a base OS). ``` #!/bin/sh curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | NIX_CHANNEL=nixos-20.03 bash 2>&1 | tee /tmp/infect.log ``` ## Motivation Motivation for this script: nixos-assimilate should supplant this script entirely, if it's ever completed. nixos-in-place was quite broken when I tried it, and also took a pretty janky approach that was substantially more complex than this (although it supported more platforms): it didn't install to root (/nixos instead), left dregs of the old filesystem (almost always unnecessary since starting from a fresh deployment), and most importantly, simply didn't work for me! (old system was being because grub wasnt properly reinstalled)
