Verbose output

[kosli]

I see that the mydumper verbosity level is set to 3 (0 = silent, 1 = errors, 2 = warnings, 3 = info. Default is 2.). Is there a reason to not leave it on the default level, so the output of the container would be more quiet? In general it would be nice if the container outputs ONLY information if there is a problem (instead of the informational printf about creating directories etc). What do you think?
