path: root/sys-kernel/dracut/files/043-0002-Replace-echo-n-with-printf-in-code-wit.patch

From 15f330fe1afe9ac8870461faad55b7d63e791aca Mon Sep 17 00:00:00 2001
From: Mike Gilbert <floppym@gentoo.org>
Date: Tue, 14 Jul 2015 22:22:14 -0400
Subject: [PATCH 2/3] Replace echo -n with printf in code with a /bin/sh
 shebang

POSIX does not mandate that echo support the -n parameter.
printf has more well-defined behavior.
