The old behavior was odd in this case where it could mount the file into a subdirectory of the path we requested (not desirable) and it was named after the parent source.
E.g. if you have an image source "foo" and you specify a file-based source at mount point '/some_file', it would mount this file as "/some_file/foo".

I think this may have been a mistake from the refactor
