Les playbooks sont généralement faits pour pouvoir être lancés plusieurs fois. Là à chaque lancement il va ajouter la ligne dans la config. C'est probablement pas bloquant, mais c'est pas super.
On pourrait modifier le script shell pour qu'il n'ajoute la ligne que si elle n'est pas déjà présente. Mais une solution plus propre c'est d'utiliser lineinfile par exemple.

Idéalement on aimerait qu'il ne reboot que si la ligne au dessus a effectivement été ajoutée. C'est pas indispensable mais c'est plus agréable.
Il y a ce tuto par exemple qui explique comment faire : https://raymii.org/s/tutorials/Ansible_-_Only-do-something-if-another-action-changed.html.
