I want to automate installing Emacs packages with Cask, Puppet, and Vagrant.

Steps to reproduce
I can do this manually in Emacs on my Mac:
$ emacs M-: (cask-install) C-x C-c This successfully installs my favorite cask packages, allowing me to use them in my .emacs.
I can also do this as an inline bash command:
$ emacs -q --eval "(progn (require 'cask \"~/.cask/cask.el\") (cask-initialize) (setq save-abbrevs nil) (cask-install) (kill-emacs))" I can also do this inside Vagrant:
$ vagrant ssh vagrant@precise64$ emacs -q --eval "(progn (require 'cask \"~/.cask/cask.el\") (cask-initialize) (setq save-abbrevs nil) (cask-install) (kill-emacs))" I can even do this with sudo inside Vagrant, which will become helpful later, so that Puppet doesn' write my Emacs files as root.
vagrant@precise64$ /usr/bin/sudo -u vagrant /usr/bin/emacs -q --eval "(progn (require 'cask \"~/.cask/cask.el\") (cask-initialize) (setq save-abbrevs nil) (cask-install) (kill-emacs))" However, when I try to execute the command from a Puppet script as exec { ... }, it fails for some reason.
command => "/usr/bin/sudo -u vagrant /usr/bin/emacs -q --eval \"(progn (require 'cask \\\"~/.cask/cask.el\\\") (cask-initialize) (setq save-abbrevs nil) (cask-install) (kill-emacs))\"" Trace

command => "/usr/bin/sudo -u vagrant /usr/bin/emacs -q --eval \"(kill-emacs)\"" But that fails as well.
Some more context
I'm writing a Vagrant configuration for a crazy development environment, with lots of programming languages and text editors. I plan to add packages for D, Dart, Go, Rust; and to configure nano and maybe R Studio. Since I'm encountering errors, I'm keeping my Vagrant setup small for now: git, Vim, and Emacs.
While working on the Puppet configuration for Vim, I discovered that some commands need special shell environment configurations, like ensuring that HOME is set to /home/vagrant. I tried this with the emacs command, but it's not enough.
I even tried supplying all of the environment variables from the normal vagrant user bash shell to the emacs command, but that didn't work either.
Burning questions
- What does
emacs -q --eval ...require that Puppet/sudo are not offering? - Can I supply more options to emacs and/or Puppet to get the failing command to print a more specific error message?
Specs
I'm using:
- Cask 0.5.2
- Emacs 24 on my Mac and in Vagrant
- Ubuntu Precise Pangolin 12.04 x64
- VirtualBox 4.3.6
- Vagrant 1.4.3
- Homebrew 0.9.5
- Mac OS X 10.9.1 Mavericks
But I'm pretty sure the error is due to a misconfiguration on my part in manifests/default.pp Puppet script rather than any bug in the software stack.
