We're talking about what to do with for older kernels, and in cases when the kernel cannot promptly obtain sufficient entropy without external sources. The kernel's job is to mix in entropy from natural activity. Boot-time acquisition of non-trivial entropy by other means falls outside the kernel, and may be needed when the kernel cannot obtain sufficient entropy on its own in a timely manner. -- Viktor.
