Using the Jitter RNG core, the rngd provides an entropy source that feeds into the Linux /dev/random device if its entropy runs low. It updates the /dev/random entropy estimator such that the newly provided entropy unblocks /dev/random. The seeding of /dev/random also ensures that /dev/urandom benefits from entropy. Especially during boot time, when the entropy of Linux is low, the Jitter RNGd provides a source of sufficient entropy. endef define Package/$(PKG_NAME)/install $(INSTALL_DIR) $(1)/etc/init.d $(INSTALL_BIN) ./files/$(PKG_NAME).init $(1)/etc/init.d/$(PKG_NAME) $(INSTALL_DIR) $(1)/sbin $(INSTALL_BIN) $(PKG_BUILD_DIR)/$(PKG_NAME) $(1)/sbin/$(PKG_NAME) endef $(eval $(call BuildPackage,$(PKG_NAME)))
