Hi,

The playbook below should generate a file with the content:
a,b
ssh_host_key
ssh_rsa_host_key

However, the way I construct the variable names results in either 
syntax/templating errors or 'variable name does not exists'.

---
- hosts: localhost
  connection: local

  vars:
    CentOS:
      ciphers: "a,b"
      hostkeys:
        - "ssh_host_key"
        - "ssh_rsa_host_key"
  tasks:
  - copy:
      dest: "{{ playbook_dir }}/test.out"
      content: |

        # This works:
        {{ CentOS.ciphers }}

        # This results in 'No variable found with this name':
        {# Ciphers {{ lookup('vars', ansible_distribution + '.ciphers') }}

        # Templating errors:
        {% for hostkey in {{ lookup('vars', ansible_distribution + 
'.hostkeys') }} %}
        {{ hostkey }}
        {% endfor %}

        # Templating errors:
        {% for hostkey in {{ 
hostvars[inventory_hostname][ansible_distribution + '.hostkeys'] }} %}
        {{ hostkey }}
        {% endfor %}


What is the proper way to 'assemble' the variable names? Or is there a 
better way of doing this?

Regards,
Willem.
