The boot-loader injects randomness into the kernel before starting the kernel (using the saved random seed file), so you can have randomness from the very first bit of initialization.

If you cannot guarantee that the entropy has never been used before, that's bad.

It is guaranteed to not be worse than no injected entropy at all, which is the default and only possible alternative state before the kernel starts, it always gets mixed with what can be gathered.
