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>

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