 ### OVHcloud

 Before executing the install script, you may need to check your mounts with `df -h`. By default, OVH adds a relatively short in memory `tmpfs` mount on the `/tmp` folder, so the install script runs short in memory and fails. Just execute `umount /tmp` before launching the install script. Full install process described [here](https://lyderic.origenial.fr/install-nixos-on-ovh)

 Tested on Cloud VPS. Contabo sets the hostname to something like `vmi######.contaboserver.net`, Nixos only allows RFC 1035 compliant hostnames ([see here](https://search.nixos.org/options?show=networking.hostName&query=hostname)). Run `hostname something_without_dots` before running the script. If you run the script before changing the hostname - remove the `/etc/nixos/configuration.nix` so it's regenerated with the new hostname.

+### Scaleway
+As of November 2020, it is easy to get a NixOS VM running on Scaleway by using nixos-infect and Scaleway's support for cloud init.  
+All that is needed is to follow the nixos-infect recipe for Digital Ocean, removing the Digital Ocean-specific stuff.  
+So, pragmatically, start an Ubuntu or Fedora VM and use something like the following as your cloud-init startup script:
+```cloud-init
+#cloud-config
+write_files:
+- path: /etc/nixos/host.nix
+  permissions: '0644'
+  content: |
+    {pkgs, ...}:
+    {
+      environment.systemPackages = with pkgs; [ tmux ];
+    }
+runcmd:
+  - curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect |  NIXOS_IMPORT=./host.nix NIX_CHANNEL=nixos-22.10 bash 2>&1 | tee /tmp/infect.log
