Parent folders in the path are created if absent. Content can be specified in plain text or binary.

For empty file creation, content can be omitted. .. note:: If multiline data is provided, care should be taken to ensure that it follows yaml formatting standards. To specify binary data, use the yaml option ``!!binary`` .. note:: Do not write files under /tmp during boot because of a race with systemd-tmpfiles-clean that can cause temp files to get cleaned during the early boot process.
