<title>Creating the /etc/fstab file</title>
<?dbhtml filename="fstab.html" dir="chapter08"?>
<para>In order for certain programs to be able to determine where certain
partitions are supposed to be mounted by default, the /etc/fstab file is
used. Create a new file <filename>/etc/fstab</filename> containing the
following:</para>
<para>The <filename>/etc/fstab</filename> file is used by some programs to
determine where partitions are to be mounted by default, which file systems
must be checked and in which order. Create a new file systems table like
this:</para>
<para><screen><userinput>cat &gt; /etc/fstab &lt;&lt; "EOF"</userinput>
# Begin /etc/fstab
# filesystem mount-point fs-type options dump fsck-order
# filesystem mount-point fs-type options dump fsck-order
/dev/*LFS* / *fs-type* defaults 1 1
/dev/*swap* swap swap pri=1 0 0
proc /proc proc defaults 0 0
shm /dev/shm tmpfs defaults 0 0
/dev/xxx / fff defaults 1 1
/dev/yyy swap swap pri=1 0 0
proc /proc proc defaults 0 0
shm /dev/shm tmpfs defaults 0 0
# End /etc/fstab
<userinput>EOF</userinput></screen></para>
<para><userinput>*LFS*</userinput>,
<userinput>*swap*</userinput>
and <userinput>*fs-type*</userinput> have to be replaced with the
appropriate values (/dev/hda2, /dev/hda5 and reiserfs for example).</para>
<para>Of course, replace <filename>xxx</filename>, <filename>yyy</filename>
and <filename>fff</filename> with the values appropriate for your system --
for example <filename>hda2</filename>, <filename>hda5</filename> and
<filename>reiserfs</filename>. For all the details on the six fields in this
table, see <userinput>man 5 fstab</userinput>.</para>
<para>When adding a reiserfs partition, the <userinput>1 1</userinput> at
the end of the line should be replaced with <userinput>0 0</userinput>.</para>
<para>When using a reiserfs partition, the <emphasis>1 1</emphasis> at the
end of the line should be replaced with <emphasis>0 0</emphasis>, as such a
partition does not need to be dumped or checked</para>
<para>A tmpfs mount is added at /dev/shm to comply with Posix shared memory
requirements. For more information, see the file
Documentation/filesystems/tmpfs.txt in the kernel source tree.</para>
<para>The <filename>/dev/shm</filename> mount point for tmpfs is included to
comply with Posix shared memory requirements. For more information on this,
see <filename>Documentation/filesystems/tmpfs.txt</filename> in the kernel
source tree.</para>
<para>For more information on the various fields which are in the fstab
file, see <userinput>man 5 fstab</userinput>.</para>
<para>There are other lines which you may consider adding to your
<filename>fstab</filename> file. One example is the line which you must have
if you are using devpts:</para>
