Well it is easier as I thought. Should have tried by myself before having
asked here. Sharing the result. Still need to derive the var from the file
stat, but hoping it is possible:
test.yml:
# ansible-playbook -l offline -i hosts.cfg test.yml
- hosts: all
vars:
test: true
tasks:
- name: Copy config file, when test is defined
tags: copy
template:
src: templates/test.j2
dest: test.cfg
when: test
- name: Copy config file, when test is not defined
tags: copy
template:
src: templates/test.j2
dest: test.cfg
when: not test
templates/test.j2:
{% if test %}
Test is defined
{% else %}
Test is not defined
{% endif %}
A run with test=true skips the second copy task (as desired) and produces a
file, which states "Test is defined" (as desired). The other way around
with test=false
