[chef] How to configure opscode nginx properly

[Steve Hummingbird < >]

I have been running into some issues when configuring nginx using the opscode 
cookbook.
I have created a wrapper cookbook, which replaces the default config by 
putting my config into /etc/nginx/sites-available/default
However, the opscode cookbook always replaces that config with the default 
sample config. So, on every chef run the nginx cookbook notices that the 
default config is no longer there and replaces my config, then my wrapper 
cookbook notices that the config is not correct and replaces that file with 
my config again.
I was having the same issues when installing from source as well as using the 
ubuntu package installation.
So, in the end I am getting the feeling that I might be missing something 
fundamentally or a lot of other people must have been running into the same 
issue. How do I configure nginx the right way using the opscode cookbook?

Thanks, 
Steve
