+      <para>This file creates a new media directory, <filename>/media/auto</filename>
+      that will overlay any existing directory of the same name.  In this example,
+      the file, <filename>/etc/auto.misc</filename>, has a line:</para>
+
+<screen>cd   -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom</screen>
+
+      <para>that will mount a cdrom as <filename>/media/auto/cd</filename> if
+      that directory is accessed.  The <option>--ghost</option> option tells
+      the automounter to create "ghost" versions (i.e. empty directories) of
+      all the mount points listed in the configuration file regardless of
+      whether any of the file systems is actually mounted or not. This is very
+      convenient and highly recommended, because it will show you the available
+      auto-mountable file systems as existing directories, even when their file
+      systems aren't currently mounted. Without the <option>--ghost</option>
+      option, you'll have to remember the names of the directories. As soon as
+      you try to access one of them, the directory will be created and the file
+      system will be mounted. When the file system gets unmounted again, the
+      directory is destroyed too, unless the <option>--ghost</option> option
+      was given.</para>
