>Description:
In the installer images, bsdinstall appears to be running on vt0, which is by default the (video) console.  This means that any console spew, such as LOR warnings (which are ~guaranteed at present) will overwrite the installer dialogs.  Running the installer on a vt that is not the console will prevent this.
