Mnesia reports its errors to the error_logger and prints its debug
info with io:format/X. By default, the debug printouts are turned off.

Regardless of whether Mnesia prints stuff with io:format/X or not, you
need to configure your system to deal with such printouts, as any
Erlang application may have printouts.
