+# Fact: systemd
+#
+# Purpose:
+#   Determine whether systemd is the init system on the node
+#
+# Resolution:
+#   Check if the service_provider fact is systemd
+#
+# Caveats:
+#   If you override the service provider then it will return false, even if the
+#   underlying system still is systemd.
+#
+
+# Fact: systemd_version
+#
+# Purpose:
+#   Determine the version of systemd installed
+#
+# Resolution:
+#   Check the output of systemctl --version
+#
+# Caveats:
+#
+
+# Fact: systemd_internal_services
+#
+# Purpose:
+#   List all systemd internal real services + their state
+#
+# Resolution:
+#   Check the output of systemctl --list-unit-files systemd-* and parse it into
+#   a hash with the status
+#
+# Caveats:
+#
