When "autoinstall" directives are provided in either ``#cloud-config`` user-data or ``/etc/cloud/cloud.cfg.d`` validate minimal autoinstall schema adherance and emit a warning if the live-installer is not present. The live-installer will use autoinstall directives to seed answers to configuration prompts during system install to allow for a "touchless" or non-interactive Ubuntu system install.

Schema validation issues currently result in a warning log currently which can be easily ignored because warnings do not bubble up to cloud-init status output. In the case of the live-installer, we want cloud-init to raise an error to set overall cloud-init status to 'error' so it is more discoverable in installer environments. # TODO(Drop this validation When cloud-init schema is strict and errors) :raise: SchemaValidationError if any known schema values are present. r zExpected dict type but found: versionzMissing required 'version' keyzautoinstall.versionzExpected int type but found: N) isinstancedictrrtype__name__getint)rZautoinstall_cfgr r r!ris r)rr)__doc__ZloggingrtextwraprZcloudinit.cloudrZcloudinit.configrZcloudinit.config.schemarrrrZcloudinit.settingsr Zcloudinit.subpr Z getLoggerr'rrmetarstrrr"rr r r r!s0
