#!/bin/bash
# Freedombone install script intended for use with Debian Jessie
#
# Note on dynamic dns
# ===================
#
# I'm not particularly trying to promote freedns.afraid.org
# as a service, it just happens to be a dynamic DNS system which
# provides free (as in beer) accounts, and I'm trying to make the
# process of setting up a working server as trivial as possible.
# Other dynamic DNS systems are available, and if you're using
# something different then comment out the section within
# argument check and the call to dynamic_dns_freedns.
#
# Prerequisites
# =============
#
# cd ~/
# wget http://freedombone.uk.to/debian-jessie-console-armhf-2014-08-13.tar.xz
