ansible 2.2.1.0 does not evaluate variable lazily

[Steven Truong]

Hi all,

These are what I am trying:

base-ng.yml:

---

- name: Gathering the local facts from tags

  hosts: all

  gather_facts: yes

  roles:

    - facts

- include: "base_centos{{ ansible_distribution_major_version }}.yml" 

-----

base_centos7.yml:

--- 

  - hosts: all

    gather_facts: no

    roles:

    - { role: common, tags: ["base"] }

-----

ansible-playbook base-ng.yml -i "54.200.xx.xx," --private-key ~/.ssh/dev.pem  -u ec2-user -b -vvvvv

Using /home/steven/ansible/ansible.cfg as config file

statically included: /home/steven/ansible/roles/facts/tasks/pax_tags.yml

ERROR! 'ansible_distribution_major_version' is undefined

Did I do something wrong?  I am confused.

Thanks.

And when I did this:

---

- name: Gathering the local facts from tags

  hosts: all

  gather_facts: yes

  roles:

    - facts

- include: base_centos7.yml                                                                                          

  when: ansible_distribution_major_version == '7'

I got  a different error:

ERROR! Invalid role definition: None

it does evaluate variables lazily, the problem is that play includes
run at compile time, so the variable is needed before the fact
gathering happens.

I now have this two yml files and ansible-playbook works.  Cross my fingers....
