I was also thinking about the other modules that user service-runner. Backup at least does so.
I also think there needs to be more explanation as to the history and what has changed plus some instructions on how to check to see if the old version is in use & how to uninstall it.
Am I right in thinking that the SD and/or the EmonPi uses /var/www/html/emoncms?
As part of this could an explanation of what service-runner actually does and why an installer may wish to use it or where it is a dependency please.
