In fact, maybe that's the right policy. Avoid a boot-time parameter by just
saying

  "if you have hardware random number generation, we can fill entropy
immediately"

No kernel command line needed in practice any more. That's assuming any
kernel developer will have an IvyBridge or newer.

The "I don't trust my hardware" people can still disable that with
"nordrand".

Hmm?
