[9415459] | 197 | <para>This file creates a new media directory, <filename>/media/auto</filename>

| 198 | that will overlay any existing directory of the same name. In this example,

| 203 | <para>that will mount a cdrom as <filename>/media/auto/cd</filename> if
|
---|
| 204 | that directory is accessed. The <option>--ghost</option> option tells
|
---|
[32d0e29] | 205 | the automounter to create <quote>ghost</quote> versions (i.e. empty
|
---|
| 206 | directories) of all the mount points listed in the configuration file
|
---|
| 207 | regardless whether any of the file systems are actually mounted or not.
|
---|
| 208 | This is very convenient and highly recommended, because it will show you
|
---|
| 209 | the available auto-mountable file systems as existing directories, even
|
---|
| 210 | when their file systems aren't currently mounted. Without the
|
---|
| 211 | <option>--ghost</option> option, you'll have to remember the names of the
|
---|
| 212 | directories. As soon as you try to access one of them, the directory will
|
---|
| 213 | be created and the file system will be mounted. When the file system gets
|
---|
| 214 | unmounted again, the directory is destroyed too, unless the
|
---|
| 215 | <option>--ghost</option> option was given.</para>
