| 251 | This file creates a new media directory,
|
|---|
| 252 | <filename>/media/auto</filename> that will overlay any existing
|
|---|
| 253 | directory of the same name. In this example, the file,
|
|---|
| 254 | <filename>/etc/autofs/auto.misc</filename>, has a line:
|
|---|
| 255 | </para>
|
|---|
| 256 |
|
|---|
| 257 | <screen>cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom</screen>
|
|---|
| 258 |
|
|---|
| 259 | <para>
|
|---|
| 260 | that will mount a cdrom as <filename>/media/auto/cd</filename> if
|
|---|
| 261 | that directory is accessed. The <option>--ghost</option> option tells
|
|---|
| 262 | the automounter to create <quote>ghost</quote> versions (i.e. empty
|
|---|
| 263 | directories) of all the mount points listed in the configuration file
|
|---|
| 264 | regardless whether any of the file systems are actually mounted or not.
|
|---|
| 265 | This is very convenient and highly recommended, because it will show
|
|---|
| 266 | you the available auto-mountable file systems as existing directories,
|
|---|
| 267 | even when their file systems aren't currently mounted. Without the
|
|---|
| 268 | <option>--ghost</option> option, you'll have to remember the names of
|
|---|
| 269 | the directories. As soon as you try to access one of them, the
|
|---|
| 270 | directory will be created and the file system will be mounted. When
|
|---|
| 271 | the file system gets unmounted again, the directory is destroyed too,
|
|---|
| 272 | unless the <option>--ghost</option> option was given.
