From 7793e4bc195201c6c01582e79a2f323adcd35170 Mon Sep 17 00:00:00 2001
From: Jay Larson <jlarson@snaplinux.org>
Date: Sun, 26 Nov 2017 18:21:10 -0600
Subject: [PATCH] The following changes were made

  * Removed non POSIX redirects
  * Removed setting of loopback up (seems to do this on its own?)
  * Corrected $verbose variable check (was -z, should be -n)
  * Added quotes for ip route command around $iface (colon was a problem)
  * Should note that v1.2 was incorrectly set in Makefile previously
