It is an i386 machine.. how do I know if the port supports that?
- how do I turn that on?
- why do I want to turn that on?
- how serious is it, in reality?
- if the port does not support it then how can I disable the warning?
- if it is necessary, why is it not the default?
- how do I generate the 'entropy' that is loaded?
- how can it be entropy, if it is loaded from the bootblocks?
- what stored it in the bootblocks?
I'm asking these questions because I can't find any documentation about
this warning, which appears twice during every normal boot on my laptop
(which is shutdown -p when unused, since I am off grid). I guess that if
this is part of the rnd(4) pseudo-device then there should be a
DIAGNOSTICS section there explaining what this message means and what to
do about it..
