Controlling cloud server initiation

You can configure your cloud server so that when it is started or restarted, it initiates operation in any of several ways:

• Boot from drive if you want to boot from the read-only drive configured with your server.

• Boot from personality if you want to inject your own files into the boot process.

• Boot from cloud-init if you want to customize your boot with a cloud-init config file.
