From b4897d1c279de97cb777b5aa2b08d7365b320dd5 Mon Sep 17 00:00:00 2001 From: James Slagle Date: Thu, 4 Dec 2014 15:03:08 -0500 Subject: [PATCH] Allow injecting arbitrary yum repo configuration Allows specifying the path to a yum repo configuration file to be used during the image build process. The repo configuration file is removed at the end of the build. This is useful in that it allows using any arbitrary repo configuration during an image build.
