Yes - use a supported OS! We do have an article which explains how to workaround this: When using (unsupported) CentOS, a new, frequent warning occurs since 617/123 ISR9. Can the warning be suppressed? Note that whilst that article does give an environment variable to suppress the message, it makes it very clear that this does not mean that CentOS is implicitly supported by doing this. It's at your own risk. Using the env var given does fix the problem though (I tried it). Andrew.Image may be NSFW.
