Comment 3 for bug 655837

Looking at this, it seems like the 0.7.0 release covers most of the amazon changes (they added some sysvinit stuff, some yum install 'abstraction' as well, they adjusted subprocess exception throwing). They also added in a somewhat abstraction of yum/apt... They write out yum repo config files (thats different), and handle yum upgrades a little differently.... The 0.7.0 are more extensive (and imho better) so this bug might not be needed anymore...

Noteable additions:

1. It seems like they also can take base64 encoded userdata (from a response header??)

decoded_user_data = base64.urlsafe_b64decode(user_data)
                for header in valid_headers:
                    if decoded_user_data.startswith(header):
                        returned_data = decoded_user_data
                        break

2. It seems like they have a generic package install mechanism we might want to take (a config module):
   a) Look for file (in that rpm), cc_package_setup.py

3. Similarly they generate repo configs, in cc_genrepo.py (might be useful again)
