For some reason it's writing into `/var/run/rackspace-monitoring-agent.pid`. `/var/run` is sym-linked to `/run` and that's by default `rw-r--r--` owned by root. So I thought about whether let it run as root or write pid file elsewhere (or change permission of `/run` in puppet). I guess the real agent runs as root (apt-get install) so it probably will need permission for some other stuff?
