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>

23<literal># Begin /etc/fstab

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>
