    24 <para>When a Linux system starts up without much operator interaction, the
    25 entropy pool, data used to compute a random number, may be in a fairly
    26 predictable state.  This creates the real possibility that the number generated
    27 at startup may always be the same.  In order to counteract this effect,
    28 you should carry the entropy pool information across your shut-downs and
    29 start-ups.</para>
