Feature: Command to initialize Rugged TUF repository locally.
  In order to host TUF metadata
  As an administrator
  I need to initialize a TUF repo locally.

  Background:
    Given I reset Rugged
    And local Rugged directories exist

  Scenario: The 'initialize' Rugged command exists.
    When I try to run "sudo sudo -u rugged rugged initialize --help"
    Then I should not get:
      """
      Error: No such command 'initialize'.
      """
    And I should get:
      """
      Usage: rugged initialize [OPTIONS]
      
        Initialize a new TUF repository.
      
      Options:
        --local  Generate keys locally, rather than delegating to the root worker.
        --help   Show this message and exit.

  Scenario: Initialize repository locally.
