The installer (via galaxy_colleciton) will no longer create an 'admins' group. The first time the user logs in (or anytime the want to create an admin), they will:
 
1) Login
2) Create a new user or modify an existing user, and select the SuperUser checkbox. This would add the django is_superuser flag to the user and grant the them all the permissions in the system without having to manage them via a group
 
The UI will need to have the SuperUser checkbox added. The API will need to handle the logic of adding all the permission to a user that has been given 'SuperUser'.
 
Post installation the Django admin user created by the pulp_installer will not have any fo the AH permissions. The user will need to log into AH using the Django admin user and create a new admin account, setting the Super User option to true.
