I would say nothing... Following playbook snippet is just enough to go from
bare minimal Fedora 23 to Fedora 23 which can run Ansible modules:

- hosts: vm_templates
  gather_facts: False
  tasks:
  - name: install packages for ansible support
    raw: dnf -y install python python2-dnf

Maybe we can get a patch to ansible which prints a useful hint when Python 2
interpreter is not found on the target system?

I mean something like:
"Huh, there is no Python 2 on the system <hostname>.
Please use gather_facts: False & raw module to install Python 2 package."

It would help even to users who do not use kickstarts, e.g. when you download
a image from somewhere and it does not work with Ansible by default.
