+    <title>Notes</title>
+
+    <para>These commands are implemented in a way that preserves basic compatibility with the original SysV
+    commands.  <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    verbs <command>halt</command>, <command>poweroff</command>, <command>reboot</command> provide the same
+    functionality with some additional features.</para>
+
+    <para>Note that on many SysV systems <command>halt</command> used to be synonymous to
+    <command>poweroff</command>, i.e. both commands would equally result in powering the machine off. systemd
+    is more accurate here, and <command>halt</command> results in halting the machine only (leaving power
+    on), and <command>poweroff</command> is required to actually power it off.</para>
