<title>Creating the mtab symlink</title>
|
|
<?dbhtml filename="mtablink.html" dir="chapter06"?>
|
|
|
|
<para>The next thing to do is to create a symlink pointing from
|
|
<filename>/etc/mtab</filename> to <filename>/proc/mounts</filename>.
|
|
This is done using the following command:</para>
|
|
|
|
<para><screen><userinput>ln -sf /proc/mounts /etc/mtab</userinput></screen></para>
|
|
|
|
<para>Creating this symlink avoids problems which can occur if
|
|
<filename class="directory">/</filename> is mounted read-only and the
|
|
information in <filename>/etc/mtab</filename> is stale (i.e. out of date).
|
|
By creating the symlink to <filename>/proc/mounts</filename>, we ensure that
|
|
the information on currently mounted devices is always up-to-date.</para>
|
|
|
|
<para>Note that using this symlink requires that you have support for the
|
|
proc filesystem compiled into your kernel. This support is included by
|
|
default, and should not be removed unless you <emphasis>really</emphasis>
|
|
know what you are doing, as some more things besides the
|
|
<filename>/etc/mtab</filename> symlink depend on proc being present.
|
|
In short, make sure you have proc filesystem support in your kernel.</para>
