I’ve got a playbook in which I’m trying to use add\_host to dynamically generate a group of hosts. Here’s what I have:

\roles  
\ group\_servers  
\ tasks  
\ main.yml  
\ common  
\ tasks  
\ main.yml  
setup.yml

==\> ./roles/group\_my\_servers/tasks/main.yml

tested by moving add\_host from role over to “tasks” - same result. Sounds like I’m missing the point someplace, but where?
