You mentioned in http://doughellmann.com/2015/03/07/ansible-roles-for-python-developers.html that you'd be interested in potentially supporting Fedora at some point. Unfortunately, Ansible doesn't make that particularly easy, since it doesn't abstract away the cross-distro differences in package management at all. That means you'd need:

• a way to use yum/dnf instead of apt to install system dependencies: https://serverfault.com/questions/587727/how-to-unify-package-installation-tasks-in-ansible
• a way to use either https://softwarecollections.org or https://copr.fedoraproject.org/ as the provider of additional Python versions
