I understand that $cookie_domain value needs to be changed in the settings.php file to $cookie_domain = "www.yoursite.com"; . My host Omega8.cc, which is a very popular aegir host uses the global.inc file to set this value.

I've been told by their support team it isn't possible to include this value in the settings.php file and that this value could be read by your awesome! module from the global.inc file.

Please consider supporting the global.inc file.
