Cannot use :path => '..' in Cheffile

[tknerr]

When you have Cheffile inside a cookbook directory, and then try to resolve that via :path it fails because it can not copy to itself (see stacktrace below).

Cheffile

cookbook "foo",
  :path => '..'

For me this is a common scenario. Typically I have both Cheffile and Vagrantfile inside a cookbook's directory so I can do a librarian-chef install && vagrant up for a testing the cookbook in a Vagrant VM.

Until now I have to set chef.cookbooks_path = [ './cookbooks', '..' ] in the Vagrantfile to make both the resolved dependencies and the cookbook itself (via '..') available in vagrant.

This is bad because it potentially includes lots of other cookbooks from '..' which can cause all sorts of trouble, so I consider it broken.

That's why I added cookbook "foo", :path => '..' to Cheffile so that all cookbooks including "self" are resolved to ./cookbooks. Then the chef.cookbooks_path = [ './cookbooks' ] in theVagrantfile` is properly isolated again.
