#TODO: Test with lucid/maverick/natty, make separate workstation/server versions. Workstation uses /home/matt/.gemrc (instead of /root/.gemrc) and rails s for hosting, while the server uses nginx + Passenger. Locally, chown -R matt:matt first_app/ to get `rails s` working. Although when you run `rails new blah` as matt, blah is owned by matt. Whatever.
#TODO: Test on CentOS, Debian 5, Debian 6, Ubuntu LTS, Maverick, Natty.
