You aren't dumping and restoring the entropy pool; you are dumping random data generated by the pool, and using that data to stir the new entropy pool after the next boot. There is no direct relationship between the entropy of the old and new pools. The kernel needs to decide how much entropy you added based on how much random data you provide it with to stir the pool. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
