cloud-init-datasources

cloud-init-datasources

Configures cloud-init to only use an explicit list of data sources.

Cloud-init contains a growing collection of data source modules and most are enabled by default. This causes cloud-init to query each data source on first boot. This can cause delays or even boot problems depending on your environment.

Including this element without setting DIB_CLOUD_INIT_DATASOURCES will cause image builds to fail.
