Although someone getting root access on the host would be able to do the same things as the nydus-snapshotter to generate its own credentials, it would still be better to not write them to disk at all. Proposed Improvement I think there are a few things to discuss there: What do we write to disk? Nothing at all? Or the nydusd config but missing the creds that will have to be passed using another method If we don't write the config at all, how do we ensure nydusd gets access to its config fast enough so that it can start properly?
