- <indexterm zone="ch-bootable-fstab"><primary sortas="e-/etc/fstab">/etc/fstab</primary></indexterm>
- <para>The <filename>/etc/fstab</filename> file is used by some programs to
- determine where file systems are to be mounted by default, which
- must be checked and in which order. Create a new file systems table like
- this:</para>
- <screen><userinput>cat > /etc/fstab << "EOF"</userinput>
- # Begin /etc/fstab
- # file system 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
- sysfs /sys sysfs 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>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 <command>man 5 fstab</command>.</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
- allow enabling POSIX shared memory. Your kernel must have the required support
- built into it for this to work -- more about this in the next section. Please
- note that currently very little software actually uses POSIX shared memory.
- Therefore you can consider the <filename>/dev/shm</filename> mount point
- optional. For more information, 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>
- <screen>usbfs /proc/bus/usb usbfs defaults 0 0</screen>
- <para>This option will of course only work if you have the relevant support
- compiled into your kernel.</para>
