Rails 3 "RAILS_ENV not defined by config/boot" error

[John-Paul Bader]

Hey guys,

actually I was running my new blog on rails3 and unicorn. I wanted to post about it here but didn't have the time yet. Indeed you just need unicorn - not unicorn rails. It seems to run all really well - I just need to modify my rc script a bit.

Kind regards, John
