Configuration for remote servers can be specified in ``configs``, but for convenience it can be specified as key value pairs in ``remotes``. This module can install rsyslog if not already present on the system using the ``install_rsyslog``, ``packages``, and ``check_exe`` options. Installation may not work on systems where this module runs before networking is up. .. note:: On BSD cloud-init will attempt to disable and stop the base system syslogd. This may fail on a first run. We recommend creating images with ``service syslogd disable``.
