+- Ansible Galaxy Rollen müssen installiert sein

 Die Server werden mit ihren FQDNs im Ansible Inventory hinterlegt, bedenkt das für eure ssh-config.

 ## Gruppen-Variablen
 Viele Variablen sind Mesh-spezifisch und werden auf allen Gateways benötigt. Deshalb verwalten wir die Liste `meshes`. Jeder Listeneintrag ist ein Dictionary. Diese Liste befindet sich in der Sondergruppe `all` (inventory/group_vars/all) und steht damit allen Hosts im Inventory zur Verfügung.
 Diese Liste ist quasi das Herzstück zur Konfiguration der Mesh-spezifischen Parameter auf den Freifunk-Gateways. Jedes Dictionary repräsentiert eine Mesh-Wolke/Domain/Layer2-Netzwerk und ist wie folgt aufgebaut (Beispiel Mainz):
