From 09280615a0d924b3ab79acbff950f92c3420fd76 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Wed, 1 Feb 2012 12:01:58 -0500 Subject: [PATCH] merge_config.sh: Use the first file as the initial config Take the first config fragment and use it verbatim as the initial config set. This avoids running the verification loop for the first file, as nothing has actually been merged at this point. This significantly increases performance for large config fragments.
