## The installation environment
At install time, the live-server environment is just that, a live but ephemeral copy of Ubuntu Server. This means that Cloud-init is present and running in that environment, and existing methods of interacting with Cloud-init can affect the live-server. For example, if a cloud-config is presented to the live-server containing [`ssh_import_id`](https://cloudinit.readthedocs.io/en/latest/topics/modules.html?highlight=ssh#ssh-import-id), then ssh keys will be added to the authorized_keys list for the installation environment.

## First boot configuation of the target system
Autoinstall data may optionally contain a [user-data](autoinstall-reference.md#user-data) section, which is cloud-config data that is configuring the target system.
Autoinstall data may optionally contain a [user-data](autoinstall-reference.md#user-data) sub-section, which is cloud-config data that is used to configure the target system on first boot.
Subiquity itself delegates some configuration items to Cloud-init, and these items are processed on first boot.
Starting with Ubuntu 22.10, once Cloud-init has performed this first boot configuration, it will disable itself.
