# This script should finish quickly. The goal is to obtain a VM with Guest
# Additions as quickly as possible. We postpone the creation of the custom user
# account to 3.sh so that the image taken after 2.sh does not have any other
# user.
#
# 1.sh should contain all non-idempotent operations; 2.sh must be idempotent.
