Some useful lines for my Vagrantfiles

gistfile1.rb

# To have the last stable version of Chef (10.14.4)

# with the official Vagrant boxes
config.vm.provision :shell,
  :inline => "gem search -i chef -v 10.14.4 || gem install chef -v 10.14.4 --no-rdoc --no-ri"

# with the official Opscode boxes
config.vm.provision :shell,
  :inline => "/opt/chef/embedded/bin/gem search -i chef -v 10.14.4 || /opt/chef/embedded/bin/gem install chef -v 10.14.4 --no-rdoc --no-ri"


# To have my favourite text editor installed inside the vagrant without add to the Chef recipes
config.vm.provision :shell,
  :inline => "dpkg -l vim | grep -q '^ii  vim' || ( sudo apt-get update && sudo apt-get install -y vim )"

I have those lines added before the config.vm.provision :chef_solo do ... or config.vm.provision :chef_client do ... ones.

There is an improved version in https://gist.github.com/3800745
