Hi! After the rain of commits :) two hours ago a few things got broken. There is a new patch at http://drupal.org/node/42886 , http://drupal.org/files/issues/system_weights_3.patch which moves the adding of weight column to system table from update.inc to very early in update.php -- otherwise the bootstrap in update.php fails. admin/modules is also broken but jakeg http://drupal.org/node/43835 nicely fixed it. So, if you want to spend your Sunday w/ latest HEAD, then apply these. Thanks for your patience and have fun with hacking core! Regards NK
