I noticed a few things that were bugging me in the output of the integration-cli tests. - one of the tests used println to stdout so we had garage sent to the screen - some of the test, in their final log message, didn't include the name of the group/file e.g. daemon - run,iptables was just run,iptables And yes, I noticed this because I'm anal :-) but also because we should keep the output of the tests as clean as possible so its easy to spot it when things go bad.
