# NOTE: THIS PLAYBOOK IS COMPLETELY UNSUPPORTED! IT WORKED FOR ME WHEN
# DEPLOYING HOSTS FROM SCRATCH, BUT IT MAY BLOW UP YOUR KITCHEN, HURT YOUR
# PET(s), PUNCTURE YOUR CAR TYRE, OR POISON YOUR CHILDREN WITH FOOD. NOT LEAST,
# IT MIGHT SEVERELY SCREW UP THE SYSTEM(s) YOU ARE TRYING TO RUN IT AGAINST.
#
# YOU GET TO KEEP THE PIECES WHEN THAT HAPPENS. DON'T COME CRYING.
