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:
|
|
- Fedora 33 x64
|
|
- 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)
