Assuming I made some changes to the source code.
My production environment runs on passenger and nginx.
How do I restart passenger and nginx with minimal downtime?
Surely I can't do a "w" on the terminal because a server will not
always be in zero load.
Would love to hear some recommendations.
PS- I have read on unicorn (http://github.com/blog/517-unicorn) but
would love to hear what we can do for passenger.
