This should clear up some of the confusion with random number generators and drivers that obtain entropy from the hardware. Also, many hardware number generators have limited bandwidth, so it's natural for their output to be only used for seeding a random number generator.

This option signifies that the kernel's random number APIs are
|
|
permitted to return values that are not truly random.
|
|
This capability is provided for testing purposes, when a truly random
|
|
number generator is not available. The non-random number generator
|
|
should not be used in a production environment.
