From e53c0e2586bc6f4677db3c6898a6428283a6b785 Mon Sep 17 00:00:00 2001
From: Alexander Kanavin <alex.kanavin@gmail.com>
Date: Fri, 20 Jan 2017 13:33:05 +0200
Subject: [PATCH] Add support for prefixing /etc from RPM_ETCCONFIGDIR
environment variable
This is needed so that rpm can pick up target-specific configuration
from target rootfs instead of its own native sysroot.
Upstream-Status: Inappropriate [oe-core specific]
