# provisioning NixOS is provisioned by running [nixos-infect](https://github.com/elitak/nixos-infect) over a default image. > Contabo sets the hostname to something like vmi######.contaboserver.net, Nixos only allows RFC 1035 compliant hostnames (see here). > 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. ``` curl -LO https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect bash nixos-infect ```
