no platform verification task created along the first platform

During the install, we have a dialog at the end that shows the status of the platform verification task that's supposed to get executed when you run hosting setup. In my HEAD install here, such a task never gets created, even though the platform node gets created.

mysql> select * from hosting_task;
Empty set (0.00 sec)

mysql> select * from hosting_task_log;
Empty set (0.00 sec)

mysql> select * from hosting_platform;
