     I understand the need for good random sources, and won't argue
it.  My question is, how can we tell what random sources a system
actually has, i.e. is there some flag that cpuctl identify shows
when a system has RDRAND/RDSEED?  Are there other sources that can
be positively identified as providing randomness?
