+              <para>As anacron, fcron does not assume that the system runs permanently.
+                 Thus, fcron features similar functionalities to anacron, but it
+                 has different means to achieve it, in other words other ways to define
+                 when a job should run. Fcron is in general much more flexible
+                 than anacron. That said,
+                 there is no strict equivalent to an anacron entry: the best would
+                 probably be to have a look at 
+                 <link linkend="fcrontab.5">&fcrontab;(5),</link> and choose the
+                 type of line which is the most appropriate for your needs (this is
+                 likely to be a @-line or a %-line).</para>
+              <para>If you insist on willing to emulate an anacron entry, as precisely
+                 as possible, you should use a %daily, %monthly or %weekly line. If
+              this doesn't emulate an anacron entry as closely as you would like,
+              you may want to try a %hours or %days line, and/or &optrunfreq;.</para>
+              <para>In any case, you would benefit from using fcron options such as 
+              &optserial; or &optlavg;.</para>

            <answer>
               <para>You should use a line similar to the following one:</para>
-              <para>@volatile,first(xx) BIG-period /your/command</para>
-              <para>where xx is the time you would have put in your anacron line.</para>
+              <para>@volatile,first(1) BIG-period /your/command</para>
+              <para>This will run /your/command one minute after every reboot.</para>
