Hm, well, _dmapi_scratch_mount tries a mount, and then does a _notrun if that fails.

Josef's patch calls a _fail (or an exit) if mount fails, and it never gets to "notrun"
in _dmapi_scratch_mount.

So for this test it's an expected mount failure, which changes things a bit.

Still, not quite sure why the test continues after either exit 1 or _fail.

But my bash is rusty...
