17  <para os="a">The <filename>/etc/fstab</filename> file is used by some
18  programs to determine where file systems are to be mounted by default,
19  in which order, and which must be checked (for integrity errors) prior
20  to mounting. Create a new file systems table like this:</para>

22<screen><userinput>cat &gt; ${CLFS}/etc/fstab &lt;&lt; "EOF"
23<literal># Begin /etc/fstab

37  <para os="b">Replace <replaceable>[xxx]</replaceable>,

41  class="partition">hda5</filename>, and <systemitem
42  class="filesystem">ext2</systemitem>. For details on the six

45  <para os="c">The <filename class="directory">/dev/shm</filename> mount point
46  for <systemitem class="filesystem">tmpfs</systemitem> is included to
47  allow enabling POSIX-shared memory. The kernel must have the required
48  support built into it for this to work (more about this is in the next
49  section). Please note that very little software currently uses
50  POSIX-shared memory.  Therefore, consider the <filename
51  class="directory">/dev/shm</filename> mount point optional. For more
52  information, see <filename>Documentation/filesystems/tmpfs.txt</filename>
53  in the kernel source tree.</para>
