From 2008713c7174e5c0f207bac684c6df0939047009 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 24 Oct 2012 14:11:48 -0700 Subject: Makefile: Documentation for external tool should be correct If one includes documentation for an external tool, it should be correct. This is not: 1. Overriding the input to rngd should typically be neither necessary nor desired. This is especially so since newer versions of rngd support a number of different *types* of sources. 2. The default kernel-exported device is called /dev/hwrng not /dev/hwrandom nor /dev/hw_random (both of which were used in the past; however, kernel and udev seem to have converged on /dev/hwrng.) Overall it is better if the documentation for rngd is kept with rngd rather than in a kernel Makefile. Signed-off-by: H.
