From 4d69fb44a5607e16843537be26758893f2dd79be Mon Sep 17 00:00:00 2001 From: Jacob Bednarz Date: Tue, 19 Jun 2018 16:04:17 -0600 Subject: Explicitly prevent `sudo` access for user module To deny a user elevated access, you can omit the `sudo` key from the `users` dictionary. This works fine however it's implicitly defined based on defaults of `cloud-init`. If the project moves to have `sudo` access allowed for all by default (quite unlikely but still possible) this will catch a few people out. This introduces the ability to define an explicit `sudo: False` in the `users` dictionary and it will prevent `sudo` access. The behaviour is identical to omitting the key.
