OSTree Support

Let's say I decide to install Pulp 2.10 and all of its plugins on Fedora 24 with the following script:

#!/usr/bin/env bash
set -euo pipefail

dnf update -y
dnf install -y git vim ansible python-dnf libselinux-python
mkdir code
cd code
git clone https://github.com/pulp/pulp_packaging
cd pulp_packaging
echo localhost > hosts
ansible-playbook -i hosts --connection local -e pulp_version='2.9' \
    ci/ansible/pulp_server.yaml

This will fail when the "Install OSTree" task executes. Here's the error returned by Ansible:

TASK [pulp : Install OSTree] ***************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: -------------

    "module_stderr": "…",
    "module_stdout": "",

Here's the contents of module_stderr:

Error Summary
-------------

If one applies the following patch to the pulp_packaging repository, then the install on Fedora 24 works just fine:
