#!/bin/bash
# relays and shell commands, but swallows any errors and always returns  with 
# an exit status of 0
#
# Useful when docker 'RUN' command receives error codes when installing
# applications that can be ignored
#
# TODO:  if the first arg starts with '-', then only filter using those
# codes.  IE: arg1="-100,101".  In this case we will swallow any 100,101
# error codes, but nothing else so any other error codes will still get
# sent back to docker RUN, which in turn will halt installation
#
# Docker command to install salt via bootstrap
