I don't think this is good news at all. Once a buildbot runs on a CF machine it immediately becomes impossible to do any meaningful measurement on that machine. That is mainly because of the random I/O (untar, rm -fr, etc.) of the bot. As a result variance goes to the roof and all measurements drown in noise. So it would be good if there was a strict separation of machines used for bots and machines used by humans. In other words bots should only run on dedicated machines. -- Markus
