Ch07 S06, Step 4 says to "Create a playbook named `use-bash_env-role.yml` that uses the `student.bash_env` role. "

The actual playbook contains about 20 lines, only two of which are related to roles. None of the other info is mentioned, but is required in the playbook. Some of the tasks are casually mentioned afterwards, but there's nothing about how the student should go about creating the playbook.

This could easily span three subtasks to make the whole step easier to digest.
