This script is intended primarily for informational purposes, and as a base for similar custom configuration scripts. Setup instructions for nihilists and other reckless individuals:

  1. Launch Ubuntu 11.10 AMI 4dad7424.
  2. Log in to the instance, and run the following commands:
curl -L https://raw.github.com/gist/3085368/_base-setup.sh | sudo bash -s
sudo su -l jenkins
curl -L https://raw.github.com/gist/3085368/_jenkins-user-setup.sh | bash -s
