                 Enable the cloud-init service. This services reads

     

       63
       +
                 configuration metadata in a cloud environment and configures

     

       64
       +
                 the machine according to this metadata.

     

       65
       +
       

     

       66
       +
                 This configuration is not completely compatible with the

     

       67
       +
                 NixOS way of doing configuration, as configuration done by

     

       68
       +
                 cloud-init might be overriden by a subsequent nixos-rebuild

     

       69
       +
                 call. However, some parts of cloud-init fall outside of

     

       70
       +
                 NixOS's responsibility, like filesystem resizing and ssh

     

       71
       +
                 public key provisioning, and cloud-init is useful for that

     

       72
       +
                 parts. Thus, be wary that using cloud-init in NixOS might

     

       73
       +
                 come as some cost.
