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>
21
22<screen><userinput>cat &gt; /etc/fstab &lt;&lt; "EOF"
23<literal># Begin /etc/fstab
24
25# file system  mount-point  type   options          dump  fsck
26#                                                         order

34  <para os="b">Replace <replaceable>[xxx]</replaceable>,
35  <replaceable>[yyy]</replaceable>, and <replaceable>[fff]</replaceable>
36  with the values appropriate for the system, for example, <filename
37  class="partition">hda2</filename>, <filename
38  class="partition">hda5</filename>, and <systemitem
39  class="filesystem">ext2</systemitem>. For details on the six
40  fields in this file, see <command>man 5 fstab</command>.</para>
41
42  <para os="c">The <filename class="directory">/dev/shm</filename> mount point
43  for <systemitem class="filesystem">tmpfs</systemitem> is included to
44  allow enabling POSIX-shared memory. The kernel must have the required
45  support built into it for this to work (more about this is in the next
46  section). Please note that very little software currently uses
47  POSIX-shared memory.  Therefore, consider the <filename
48  class="directory">/dev/shm</filename> mount point optional. For more
49  information, see <filename>Documentation/filesystems/tmpfs.txt</filename>
50  in the kernel source tree.</para>
