| 5 | <para>The next thing to do is to create a symlink pointing from
|
|---|
| 6 | <filename>/etc/mtab</filename> to <filename>/proc/mounts</filename>.
|
|---|
| 7 | This is done using the following command:</para>

| 11 | <para>Creating this symlink avoids problems which can occur if
|
|---|
| 12 | <filename class="directory">/</filename> is mounted read-only and the
|
|---|
| 13 | information in <filename>/etc/mtab</filename> is stale (i.e. out of date).
|
|---|
| 14 | By creating the symlink to <filename>/proc/mounts</filename>, we ensure that
|
|---|
| 15 | the information on currently mounted devices is always up-to-date.</para>
|
|---|
| 16 |
|
|---|
| 17 | <para>Note that using this symlink requires that you have support for the
|
|---|
| 18 | proc filesystem compiled into your kernel. This support is included by
|
|---|
| 19 | default, and should not be removed unless you <emphasis>really</emphasis>
|
|---|
| 20 | know what you are doing, as some more things besides the
|
|---|
| 21 | <filename>/etc/mtab</filename> symlink depend on proc being present.
|
|---|
| 22 | In short, make sure you have proc filesystem support in your kernel.</para>
