Why would this be? It has lots and lots of ansible\_\* variables, but some others like ansible\_hostname or ansible\_mounts.

In order to access some ansible\_\* variables you need to gather facts on the host before.

See e.g. [https://stackoverflow.com/questions/45908067/whats-the-difference-between-inventory-hostname-and-ansible-hostname](https://stackoverflow.com/questions/45908067/whats-the-difference-between-inventory-hostname-and-ansible-hostname)
