Right, and that's what I was trying to say is that if we do all that and switch out 
urandom with something new that does what we need, what's the difference in just 
patching the behavior into urandom and calling it a day? Its simpler, less fragile, 
admins won't make mistakes setting up the wrong one in a chroot, already has the 
FIPS-140 dressing, and is auditable.
