+# Nagios plugin to check the system state according to systemd.
+#
+# This plugin checks the system's state according to systemd, i.e.
+#
+#   $ systemctl is-system-running
+#   degraded
+#
+# If it reports anything other than "running", be sure to check the output of
+# these commands:
+#
+#   $ systemctl list-units
+#   $ systemctl status
