I'd prefer having an init script, but I can add it later since I'm already on to that. The hosts file seems to suggest a user called pi while ansible contains iojs. Not sure if intentional but LGTM either way as long as it works.

• yes init scripts would be awesome for these machines in particular because java regularly dies in the constrained environment, I just haven't proritised yet but am happy to have assistance!
• pi user is the default user on raspbian and has sudo access, it's used to set up the boxes, the iojs user is unprivileged and is created by the setup procedure to run the slave.

Thanks for the reply. Happy to merge.
