+<para>When using a journalling file system, the <parameter>1

+<parameter>0 0</parameter> because such a partition does not need to
+be dumped or checked.</para>
+
+<para>The <filename class="directory">/dev/shm</filename> mount point
+for <systemitem class="filesystem">tmpfs</systemitem> is included to
+allow enabling POSIX-shared memory. The kernel must have the required
+support built into it for this to work (more about this is in the next
+section). Please note that very little software currently uses
+POSIX-shared memory.  Therefore, consider the <filename
+class="directory">/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 may be added to the
+<filename>/etc/fstab</filename> file. One example is a line for USB
+devices:</para>
+
+<screen>usbfs        /proc/bus/usb usbfs   devgid=14,devmode=0660 0 0 </screen>
+
+<para>This option will only work if <quote>Support for Host-side
+USB</quote> and <quote>USB device filesystem</quote> are compiled into
+the kernel (not as a module).</para>
