This creates a specific slice which all OpenStack services will operate from. By creating an independent slice these components will be governed away from the system slice allowing us to better optimise resource consumption. See the following for more information on slices: * https://www.freedesktop.org/software/systemd/man/systemd.slice.html See for following for more information on resource controls: * https://www.freedesktop.org/software/systemd/man/systemd.resource-control.html Tools like ``systemd-cgtop`` and ``systemd-cgls`` will now give us insight into specific processes, process groups, and resouce consumption in ways that we've not had access to before. To enable some of this reporting the accounting options have been added to the [Service] section of the unit file.
