<title>Creating the /etc/fstab file</title>
<?dbhtml filename="fstab.html" dir="chapter08"?>
<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 > /etc/fstab << "EOF"</userinput>
# Begin /etc/fstab
# filesystem mount-point fs-type options dump fsck-order
/dev/xxx / fff defaults 1 1
/dev/yyy swap swap pri=1 0 0
proc /proc proc defaults 0 0
devpts /dev/pts devpts gid=4,mode=620 0 0
shm /dev/shm tmpfs defaults 0 0
# End /etc/fstab
<userinput>EOF</userinput></screen></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 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>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>There are other lines which you may consider adding to your
<filename>fstab</filename> file. One example is a line to use if you intend to
use USB devices:</para>
<para><screen>usbfs /proc/bus/usb usbfs defaults 0 0</screen></para>
<para>This option will of course only work if you have the relevant support
compiled into your kernel.</para>
