Comment 9 for bug 124993

Another option in case PolicyKit isn't ready for hardy would be to "sg stb" (or whatever group is allowed to make changes, perhaps even the "root" group) or "gksg stb", but gksu doesn't support this. This would basically gain the user additional group credentials as protected by whatever tool is picked to switch group, and these credentials would be lost when the command ends; the GConf settings would still be opened as $user.
