Bug Description

The user at https://github.com/canonical-web-and-design/ubuntu.com/issues/9515 reported that cloud-init applies the 'first boot' config more than once. This can potentially be a serious issue if the subiquity-provided cloud-init config contains low security credentials that are replaced ASAP - it would not be acceptable for cloud-init to then revert them.

Subiquity should configure the system in such a way that the setting is applied exactly once and then it is not possible for these settings to be applied again.

A behavior change has been introduced in Ubuntu Kinetic and later where cloud-init is disabled after the first-boot configuration is complete. If need be we can consider what to do for earlier versions.
