Create new user on site installation.

This is how we did it in HM1

Basically you will be taking the --site_admin_email (or something like that) item passed to drupal,
and creating a user account using this.

If you can, please see if you can change this so that it sends the confirmation mail. with the single use link instead.

if (!function_exists('user_load')) {
	include_once(drupal_get_path('module', 'user') . '/user.module');
}
$admin_user = user_load(array('uid' => 1));
if ($GLOBALS['hm_client_email'] && !$admin_user->uid) {
  $user = new stdClass();
  $edit['name'] = 'admin';
  $edit['pass'] = user_password();
  $edit['mail'] = $GLOBALS['hm_client_email'];
  $edit['status'] = 1;
  $user = user_save($user,  $edit);
	
	if (file_exists("hm/profiles/$profile/welcome_mail.inc")) {
    include("hm/profiles/$profile/welcome_mail.inc");
    include_once('hm/hm.inc');
	  // Send mail
	  $variables = array(
	    '!username' => $edit['name'], 
	    '!password' => $edit['pass'], 
	    '!uri' => 'http://' . $GLOBALS['hm_temporary_url'] . '/user/login'
	  );
	  $from = $mail['from'];
	  $admin_email = $GLOBALS['hm_admin_email'];
	  $client_email = $GLOBALS['hm_client_email'];

	  drupal_mail('hm_welcome_email', $admin_email, t($mail['subject'], $variables), t($mail['body'], $variables), $from);
	  print "Initial user registration mail sent to $admin_email\n";
	  if ($client_email && ($client_email != $admin_email)) {
		  drupal_mail('hm_welcome_email', $client_email, t($mail['subject'], $variables), t($mail['body'], $variables), $from);
		  print "Initial user registration mail sent to $client_email\n";
	  }
	
	}
	else {
		print "Welcome mail not available, initial account not created\n";
	}
 
}

This seems to have become a fairly important piece of code, as it needs to be done to get D6 working properly (as the install also creates a placeholder account for you)

The mail bit at the bottom can be replaced with this code from user.module

  $account = $form_values['account'];
  $from = variable_get('site_mail', ini_get('sendmail_from'));

  // Mail one time login URL and instructions.
  $variables = array('!username' => $account->name, '!site' => variable_get('site_name', 'Drupal'), '!login_url' => user_pass_reset_url($account), '!uri' => $base_url, '!uri_brief' => preg_replace('!^https?://!', '', $base_url), '!mailto' => $account->mail, '!date' => format_date(time()), '!login_uri' => url('user', NULL, NULL, TRUE), '!edit_uri' => url('user/'. $account->uid .'/edit', NULL, NULL, TRUE));
  $subject = _user_mail_text('pass_subject', $variables);
  $body = _user_mail_text('pass_body', $variables);
  $mail_success = drupal_mail('user-pass', $account->mail, $subject, $body, $from);

just committed a basic starting point

i'm still not receiving emails, but it's definitely my mail admin side of things that is broken.

still need configurable welcome messages and a lot of tidying up.

Adrian's code in HEAD is working for me. The admin user is created and the email is sent.

I'll work on the custom email message, something like hm1, as it uses the password reset mail text at the moment.

Done user account creation.

See http://drupal.org/node/324066 for customer user email.

put in the right project.
