  <para os="a">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 &gt; ${CLFS}/etc/fstab &lt;&lt; "EOF"
<literal># Begin /etc/fstab

# file system  mount-point  type   options          dump  fsck
#                                                         order

/dev/<replaceable>[xxx]</replaceable>     /            <replaceable>[fff]</replaceable>  defaults         1     1
/dev/<replaceable>[yyy]</replaceable>     swap         swap   pri=1            0     0

  <para os="c">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>
