driver = Selenium::WebDriver.for(:remote, :url => 'http://slave-tb2.puppetlabs.lan:4444/wd/hub/', :desired_capabilities => :chrome)
Should work to start a webdriver session with chrome... but doesn't. Works as Jenkins user from jenkins.
driver = Selenium::WebDriver.for :chrome
... works just fine.
I raise this because it works "as it should" with :remote .... :firefox.
