This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.

I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.

def local_cache(box_name)
  cache_dir = File.join(File.expand_path(Vagrant::Environment::DEFAULT_HOME),
                        'cache',
                        'apt',
                        box_name)

# Today's little useless tidbit converts a url's query string into a hash

def qs_to_hash(query_string)
  keyvals = query_string.split('&').inject({}) do |result, q| 
    k,v = q.split('=')
    if !v.nil?
       result.merge({k => v})
    elsif !result.key?(k)

Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

• Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
• We use capistrano for deployment.

Salient points for each file:
