"""
Manage nspawn containers

.. versionadded:: 2015.8.0

`systemd-nspawn(1)`__ is a tool used to manage lightweight namespace
containers. This execution module provides several functions to help manage
these containers.

.. __: http://www.freedesktop.org/software/systemd/man/systemd-nspawn.html

Minions running systemd >= 219 will place new containers in
``/var/lib/machines``, while those running systemd < 219 will place them in
``/var/lib/container``.

.. note:

``nsenter(1)`` is required to run commands within containers. It should
    already be present on any systemd host, as part of the **util-linux**
    package.
