Another way to make them much more visible would be to make
the warnings always be verbose.

In other words drop support for the "-S" options used below:

Previously the dev* stuff caused a lot of warnings, but
since we have HOTPLUG always enabled this is a non-issue.
So I think that this is a good time to enable the verboce
warnings.
