Currently we are using two: - one is already inside the appliance, it contains all the appliance defaults. It's there to loose the coupling between hosted-engine-setup and engine-setup as much as possible - the second contains user preferences (eg. the admin password) and it's generated by hosted-engine-setup and injected via cloud-init In this case is the appliance we got a new rpm (the serial console proxy) witch requires an additional answer so, to keep that principle and couple as less as possible, it's answer should go inside the appliance. As Didi proposed the best long term solution is to have a default-only mode in engine-setup so that we could get rid of the appliance answerfile. > If we do agree eventually that such an answerfile needs to be maintained > manually, I agree with Tolik, who said in a private discussion that it > should > be maintained inside the package of engine-setup.
