I currently use rvm on my dev box (osx) but I use the system ruby on my server (1.8.7 on Ubuntu 10.04)
I want to upgrade the server to 1.9.3 and have been researching the best way to do it. The server is running about four Rails applications all on version 3.2.11.
My options appear to be using rvm or alternatively using the 1.9.3 deb package and the ruby-switch gem provided by BrightBox (who also provide passenger packages)
The Brightbox packages appear to be a clean way to go but I thought I would ask a question here to see if there are any advantages or disadvantages of either approach that I have not thought about.
