We have been getting this question a few times now from first time users as well as experienced users and I'm not convinced that the bootup validator in it's present state will help to reduce the queries.
It will present a warning on the command line console and that can be easily missed by users, unless they have knowledge of this warning. If we can extend this to show warning messages on the web UI home page as well, that would really help.
