i'm in the process of doing a clean install of Radiant 1.0 on Ubuntu 11.10 with Passenger and Nginx. i followed the instructions and was able to get it installed with RVM successfully (thank you for the step by step instructions). However, i was wondering whether it is a good idea to use RVM on a production machine instead of a development machine. Are any of you doing this? Is this a bad idea? If using RVM is preferred, are you installing Radiant and Passenger in the appuser's home, and then Nginx in /opt or somewhere else? Is the best practice to install each Rails app as a separate user, or the same appuser with different directories/gem sets/etc? Lastly, i'm getting a 403 error when trying to view the site, and i think i'm missing something really obvious. Any hints on which directories/permissions i should check? Thanks.
