Nimbostratusbigpipe stderr/stdout
I noticed that a successful 'b config sync' outputs to stderr. Is this the expected behavior of bigpipe? I haven't tested any other commands.

- After reproducing the stderr output I noticed there was also some info being written to stdout. It appears that this was done to separate the events that occur on the peer (stdout) from those on the unit the pull is being executed from (stderr). I ran it both ways and this is what I got:
