instructions on coreOS website are possibly a bit off

[IPvSean]

In reference to defunctzombie's post here: https://coreos.com/blog/managing-coreos-with-ansible/

it seems like it would be better to do this in the /etc/ansible/hosts file instead of what is posted there:
ansible_python_interpreter="/home/core/bin/python"
(reason: ansible/ansible#9650) maybe something changed in Ansible?

This was the only way I could get it to work...

indeed ... ran into the same problem and validated that change fixes it
