In the discussion of whether /dev/urandom should fail and whether that 
should cause bootup to fail, it was stated:

Stacking possible solutions is certainly not a complete answer, but it 
is a good description of  a "brainstorming" phase that can be a very 
good part of software engineering! (Not just in this context...) Once 
you know that one of them is an /actual/ solution you might even be 
through, depending on the nature of the task. And until you know at 
least one, or maybe more possible solutions, you can hardly verify that 
one of them is an /actual/ solution.
