When saving configuration with S3 compatible storage as destination, I always get the question:
The bucket name should start with your username, prepend automatically?
The username seems to be in this case “AWS Access Id”. Prepending this does not seem reasonable.
Or, it would be nice if the question would be skipped if the bucket was not changed.
I think it’s trying to set you up to increase your chances of not having new bucket name denied.
There’s still no guarantee the name won’t be taken, but using your account as prefix helps this.
