I'm looking for an Opscode Chef cookbook that installs system-wide Ruby version 1.9.3, patch-level latest at the time of the run_list execution.
Have done some research and there is a Brightbox PPA available at least for Ubuntu flavors.
I wonder if there is a well written cross-platform Chef cookbook that replace old 1.8.7 Ruby by 1.9.3 or better without depending on RVM nor rbenv.
