Comportamiento

Reemplazar o combinar diccionarios (con "hash_behaviour=replace" en ansible.cfg):

# Reemplazar             # Combinar
---                   ---
  vars:                 vars:
    dict:                 merge:
      a: "valor"            dict: 
      b: "valor"              a: "valor" 
                              b: "valor"

# ¿Cómo funciona la combinación?
Tus vars [host_vars]  -->  vars por defecto [rol actual] --> vars por defecto [incluir rol]
  
  dict:          dict:              dict:
    a: "1" -->     a: "1"    -->      a: "1"
                   b: "2"    -->      b: "2"
                                      c: "3"
