# Script to generate new VNC server and SSH server keys at boot time if a certain
# file does not exist. Run this script whenever the Pi boots by adding a crontab
# entry, like this:
#
# 1) Run crontab -e
# 2) Add the following line to the end:
#
# @reboot sleep 5 && /usr/local/bin/initialize-pi.sh
#
# 3) Save and exit the crontab editor
