+  <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
