# Usage:
# 
#   ./installer.sh nextcloud_lamp.sh <IP> (<img>)
#
# See installer.sh instructions for details
#
# Notes:
#   Upon each necessary restart, the system will cut the SSH session, therefore
#   it is required to save the state of the installation. See variable $STATE_FILE
#   It will be necessary to invoke this a number of times for a complete installation
