# The first case: on a machine with nothing installed on it, does the
# installer describe that machine correctly, and does it refuse the shapes
# that machine cannot do -- with a reason someone could act on?
#
# A fresh Debian cloud image has no docker and no node, which is exactly the
# interesting case: every container shape and the webmail's host shape are
# unavailable, and the server's host shape is not. Getting this wrong in
# either direction is the difference between an installer that reads a
# machine and one that guesses.

# Run from the host with: e2e/vm/run.sh e2e/cases/survey.sh
