You could find an ansible script in this repo to install a supernode for the freifunk hood as207111 from scratch.

You just need to install a simple debian buster virtual or physical maschine and ansible.

After installation just login with your normal user and clone the whole repo in your home directory.

You must change the parameters in the playbook.yml of course! The parameters should be explained or self explaining.

Then you could start the installation with a command like ansible-playbook playbook.yml -b --ask-become-pass
