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(basebox_name)
  cache_dir = Vagrant::Environment.new.home_path.join('cache', 'apt', basebox_name)
  partial_dir = cache_dir.join('partial')
  partial_dir.mkdir unless partial_dir.exist?
 cache_dir

Chef git templates

Chef should allow creating cookbooks and chef-repo using templates. It should maintain the ability to create artifacts offline but a special switch could be supplied to knife wich will tell it to clone the remote repository rather than create a hardcoded structure.

Use cases:

knife chef-repo create --template https://github.com/fnichol/chef-bootstrap-repo knife cookbook create ntpd --template https://github.com/test/cookbook-with-minitest-and-berkshelf

Basically knife should clone the repository into folder and remove .git directory.

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
