+    <para>"Runlevels" are an obsolete way to start and stop groups of
+    services used in SysV init. systemd provides a compatibility layer
+    that maps runlevels to targets, and associated binaries like
+    <command>runlevel</command>. Nevertheless, only one runlevel can
+    be "active" at a given time, while systemd can activate multiple
+    targets concurrently, so the mapping to runlevels is confusing
+    and only approximate. Runlevels should not be used in new code,
+    and are mostly useful as a shorthand way to refer the matching
+    systemd targets in kernel boot parameters.</para>
