Re: [PATCH] Try to make urandom more random using the proper seed.

Sorry for the mess...

At least consider it as my way to tell that I think the iniscripts options
should be reviewed.

From what I see in /etc/init.d/rc, the script will not be started at runlevels
0 6 due to lines 146-161 :
	if [ $previous != N ] && [ $previous != S ]
	then
		#
		# Find start script in previous runlevel and
		# stop script in this runlevel.
		#
		suffix=${i#/etc/rc$runlevel.d/S[0-9][0-9]}
		stop=/etc/rc$runlevel.d/K[0-9][0-9]$suffix
		previous_start=/etc/rc$previous.d/S[0-9][0-9]$suffix
		#
		# If there is a start script in the previous level
		# and _no_ stop script in this level, we don't
		# have to re-start the service.
		#
		[ -f $previous_start ] && [ ! -f $stop ] && continue
	fi

If the script is still run please explain to me why, I do not understand...

Best regards,
Diego Abelenda
