Installer can detect incorrect default web group

After getting a Aegir2 up and running on Debian 7.5 (x64) I noticed some issues whenever creating a new instance of Drupal or with hostmaster itself. My problems are:

I can't change the logo or other file-based aspects of hostmaster
I can't complete the installation of Drupal site without errors because I don't have file level permission to the files directory or settings.php
If I manually fix the file permission issues then I still have issues with cache directories not being created and broken images.

So did a bit of research and I believe I found this issue with _provision_default_web_group() found in provision.drush.inc. It prioritizes the httpd user group over the www-data group.

function _provision_default_web_group() {
  $info = posix_getgrgid(posix_getgid());
  $common_groups = array(
    'www',
    'www-data',
    'httpd',
    'apache',
    'webservd',
    'nogroup',
    'nobody',
    $info['name']);

  foreach ($common_groups as $group) {
    if (provision_posix_groupname($group)) {
      return $group;
      break;
    }
  }
  return NULL;
}

It also appears that apache runs under the www-data user group and that by changing the ownership of these key directories to the www-data my issue goes away. This begs 2 questions:

1. Should we change the order of $common_groups to prioritize www-data over httpd
2. Do we have automated tests that test the installation process of aegir 2 on the debian platform?

Steps to reproduce:
1. download the config.yaml.txt and change the file extension to .yaml so it reads config.yaml
2. drop the file into https://puphpet.com/ to set the config for a vagrantfile
3. create a vagrantfile with that config
4. use the resultant vagrant file to create a bare bones vm with wheezy
5. ssh into vagrant file and run installation steps found on http://www.aegirproject.org/
6. log into your aegir instance and try to do basic things with it like using a make file to create new drupal instances.

You'll run into trouble with every action.
