This Aegir module allows you to set arbitrary custom Drupal variables for each site, such as site name and slogan, either manually through the Hostmaster Web UI, or programmatically through Web services via Aegir Services.
These variables will be put in settings.php, and so can't be overriden (or changed) through the site interface.
This module is only compatible with Aegir3.
