 +===== ansible stat register =====
 +
 +si on souhaite afficher des info sur nos actions, on peut utiliser le module stat sur un fichier par exemple, mais l'affichage des "stat" ne donne rien par defaut, il faut faire un register de l'output pour pouvoir le remonter sur notre server-node source du playbook .
