Debug output within a launch file
How do I enable debugging output (ROS_DEBUG) for a node within a launch file?

Yes. rxconsole is really what I was looking for. Screen output seems to display everything except debug information.
Just set output="screen" in the launch file as mentioned below. I prefer rqt_console over the screen. It's much easier to filter and even pause the output.
I think the ros console wiki had confusing language until I edited it just now- but to be clear there is no way to have a node launch with a specific logger level, if you want debug on to catch node start debug messages you have to go outside the launch file and edit this conf file (without going to extremes to have a launch file write DEBUG or INFO to a conf file and then load that with env, and the order of execution would probably be wrong without going to even further extremes of nested launch files)- is that right?
And there is no per-node log level capability in the conf file, just per-package?
