# This is a workaround for the lack of a python package for libselinux-python
# on PyPI. Without using --system-site-packages to create the virtualenv, it
# seems difficult to ensure the selinux python module is available. It is a
# dependency for Ansible when selinux is enabled. On CentOS 8, we can install
# the selinux package from PyPI, however when using Python 3 on CentOS 7 this
# does not work.
