    1. This is the node where juju is running on. It is the basic node in your environment and it will control all the other nodes.

    2. Yes, Zookeeper is on this node.

    3. Zookeeper is a java-application which is running as a deamon on the first node - the bootstrap node. It is runnig with the user zookeeper.

    4. If this node is destroyed, your whole environment is destroyed. You can try this by type juju terminate-machine 0. Juju won't do it and give you an error.

    5. No, one environment can have only one bootstrap node. With this node is the whole environment build and administrated, so it can't exist more then one bootrap node in this organization.
