Our problem

Became tiresome and problematic to manage 6 Mac Minis in our Selenium Grid farm, 3 of which have virtual machines

Launcher scripts

launch-rc.battitle Selenium RC [%1] [%2]ant launch-remote-control -Drc.port=%1 -Drc.environment=%2

launch-rc.shecho -n -e "\033]0;Selenium RC [$1] [$2]\007"ant launch-remote-control -Drc.port=$1 -Drc.environment="$2

launchHub.shecho -n -e "\033]0;Selenium Grid\007"cd ~/moz-grid-config/ant launch-hub

Default project properties file

Machine-specific properties files

Mac Mini properties files

Virtual-machine instances' properties files

Adding a new environment

Add a [machine-name/IP].project.properties, containing a reference to itself

git checkout master

git pull

...and that's it
