Provision installs Drupal 6 in different order to Drupal

When i'm creating a node through node_save() i can't set a path because of the limitation of path_nodeapi() (http://api.drupal.org/api/drupal/modules--path--path.module/function/pat...). In this function there is a user_access() call and the user running the installation profile is user 0, that imply that the user_access() check fails and the path attribute can't be set.

The bigger question is why the user running the installation profile isn't defined as user 1.
Here is a snippet to run if you want to reproduce the issue:

  // Create page presentation
    $node = array(
    'title' => t('Presentation'),
    'body' => t('Full description of the presentation node'),
    'nid' => NULL,
    'type' => 'page',
    'teaser' => NULL,
    'log' => '',
    'created' => '',
    'format' => FILTER_FORMAT_DEFAULT,
    'path' => 'presentation',
    'uid' => 1,
  );
  $node = (object) $node;
  node_save($node);

Thanks!
