OK, I'd not pulled the branch correctly - apologies.
In the 'you manage environments with files' use case mentioned on the
wiki, could the following be an alternative to editing a file to add a
cookbook, i.e. only the cookbook_versions line would be absent or over
ridden by the presence of a sub-folder ./development/cookbooks:

$ ls -la ~/chef-repo/environments/*
 development.rb
 production.rb
 staging.rb

development:
total 8
drwxr-sr-x 2 hedge users   22 2010-12-09 10:34 .
drwxrwsr-x 9 hedge users 4096 2010-12-09 10:34 ..
drwxr-xr-x  3 hedge users   20 2010-12-08 16:09 cookbooks

production:
total 8
drwxr-sr-x 2 hedge users   22 2010-12-09 10:34 .
drwxrwsr-x 9 hedge users 4096 2010-12-09 10:34 ..
drwxr-xr-x  3 hedge users   20 2010-12-08 16:09 cookbooks

staging:
total 8
drwxr-sr-x 2 hedge users   22 2010-12-09 10:34 .
drwxrwsr-x 9 hedge users 4096 2010-12-09 10:34 ..
drwxr-xr-x  3 hedge users   20 2010-12-08 16:09 cookbooks

Where

$ ls -la ~/chef-repo/environments/development/*

cookbooks:
total 20
drwxr-xr-x 26 hedge users 4096 2010-12-08 16:10 .
drwxr-xr-x 10 hedge users 4096 2010-12-08 16:09 ..
drwxr-xr-x  8 hedge users 4096 2010-12-08 16:10 apache2
drwxr-xr-x  5 hedge users  118 2010-12-08 16:09 application
drwxr-xr-x  5 hedge users  114 2010-12-08 16:09 apt
etc.


What benefit does this bring?
I, or my script, can update cookbooks without having to edit any
files, by installing them to a folder as follows:

bundle install --without production staging --gemfile
~/chef/app_stacks/rails.gemfile --install-path
~/chef/chef-repo/environments/development/cookbooks

There is some way to go to get bundler to fully live up to its
potential and play its complete part, but it'd be nice to have Chef's
door left open.

Appreciate the consideration.
