In the current nightly builds, the autodetected kit is pre-set to use Boot2Qt device types only. In this case it is not correct to call such a kit "Automotive" since users might need to start using it to setup their environment. Doing this they will not be able to launch any app form the Qt Creator
That kit should be either named "Boot2Qt ZZZ YYY" or setup in such a way that it would be based on the Application Manager device type.
The current version of the Application Manager plugin is made the say that it uses the Generic Linux device type as a base. Moreover, the docs tell the user to create a new kit anyways.
