NixOS is a distribution based on the Nix package manager. It allows one to declaratively configure the system and its services. This page describes NixOS specifics on vpsFree.cz's VPS. For more information about NixOS in general, see its documentation.
We provide templates for the stable releases and continually for unstable.
NixOS is used heavily at vpsFree.cz for its infrastructure and services, so we make sure that it works reliably. We use mainly the current stable release. Our virtualization platform vpsAdminOS is actually based on NixOS and nixpkgs.
The VPS is created from a template which contains a minimal system with SSH.
You can log in using a generated password
or deploy your public key using vpsAdmin.
The system can then be configured using nixos-rebuild or any other
deployment tool.
Note that our VPS are Linux containers, so there is no boot loader, the kernel is shared
and some configuration is required for the VPS to work properly. The template installs
this configuration into /etc/nixos/vpsadminos.nix, which is imported by
/etc/nixos/configuration.nix. The up-to-date configuration module
can be always found at
https://github.com/vpsfreecz/vpsadminos/blob/staging/os/lib/nixos-container/vpsadminos.nix.
