Cloudstack images are simply using cloud-init. They are not headless as a user usually have access to a console. Otherwise, the difference with Openstack are mostly handled by cloud-init. This is still some minor issues. Notably, there is no non-root user. Other cloud images usually come with a user named after the distribution and with sudo. Would it make sense for NixOS? Cloudstack gives the user the ability to change the password. Cloud-init support for this is imperfect and the set-passwords module should be declared as `- [set-passwords, always]` for this to work. I don't know if there is an easy way to "patch" default cloud-init configuration. However, without a non-root user, this is of no use. Similarly, hostname is usually set through cloud-init using `set_hostname` and `update_hostname` modules. While the patch to declare nixos to cloud-init contains some code to set hostname, the previously mentioned modules are not enabled.
