# Summary
# =======
#
# This script is intended to be run on the target device, which
# is typically a Beaglebone Black.
#
# To be able to run this script you need to get to a condition
# where you have Debian Jessie installed, with at least one
# unprivileged user account and at least one subdomain created on
# https://freedns.afraid.org/. If you're not installing on a
# Beaglebone Black then set the variable INSTALLING_ON_BBB to "no"
#
# 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_checks and the call to dynamic_dns_freedns.
#
# Prerequisites
# =============
#
# You will need to initially prepare a microSD card with a Debian
# image on it. This can be done using the initial_setup.sh script.
#
# If you are not using a Beaglebone Black then just prepare the
# target system with a fresh installation of Debian Jessie.
#
# Configuration file
# ==================
# If you don't want to edit this script directly then you can
# create a configuration file called freedombone.cfg, which should
# be in the same directory as install-freedombone.sh.
# Within the configuration file you can specify the main settings
# such as:
#
# INSTALLING_ON_BBB=yes
# SSH_PORT=2222
# MICROBLOG_DOMAIN_NAME=mydomain
# MICROBLOG_FREEDNS_SUBDOMAIN_CODE=[code]
# ...
#
# Note that there are no spaces around the equals.

# is running, and if anyone maliciously alters the time on Google's
# servers then that would certainly be newsworthy and they'd be
# likely to do something about it quickly.
