# CONSIDERATIONS									                                    #
# - No need to use 'sudo' because this script must be executed as root user.		    #
# - This script must be non-interactive, this means, no interaction with user at all:	#
# 	* No echo to standard output (monitor)						                        #
#	* No read from standard input (keyboard)					                        #
#	* Use auto-confirm for commands. Example: apt install -y <package>                  #
# - No need to remove/purge the application package becouse it's done by main script    #
#	* etc.										                                        #
