I think we should have a default one, but an option to have a
different one.

I think we should have at least 1 that follows SP800-90A, it's
clearly something some people will need.

It should at least reseed by default. Having an option to change
the default interval might make sense.

There clearly should be a way to use a source other than the one
provided by the kernel, which I think it needed for SP800-90A.
