+ 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>
