Instance Method Details

#call(env) ⇒ Object

During puppet provision vagrant links all the paths provided to ‘puppet.module_path` to temporary shared paths within the vm. It does this by looping through `puppet.module_path` and linking to /tmp/vagrant-puppet/modules-N, N being the index of the path within the module_path array. Modules need to reference this temporary directory in order to install certain files. Instead of guessing at which temporary directory it will be installed in, we generate custom facts that can be referenced within the module’s manifests.

These custom facts will be of the form: "#{name}_vagrant_module_path"
