# with the IANA ephemeral port range). This is a workaround for bug #1253482

# in use as an ephemeral port by another process. This places an explicit
# exception into the Kernel for the Keystone AUTH ports.

# package (e.g. due to installing a distro package with a dependency
# on python-virtualenv), first install the distro python-virtualenv
# to satisfy any dependencies then use pip to overwrite it.
# ... but, for infra builds, the pip-and-virtualenv [1] element has
# already done this to ensure the latest pip, virtualenv and
# setuptools on the base image for all platforms. It has also added
# the packages to the yum/dnf ignore list to prevent them being
# overwritten with old versions. F26 and dnf 2.0 has changed
# behaviour that means re-installing python-virtualenv fails [2].
# Thus we do a quick check if we're in the infra environment by
# looking for the mirror config script before doing this, and just
# skip it if so.
