    Sorry, I still don't get it.

    'df path' looks up the mountpoint. Fine, no problem with that.
    Displays it in in column 'Mounted on'. Then goes on to do
    statfs(path), and display the results.

    Can you please explain why you think that's wrong? It displayed the
    free space in the directory I _aked_it_. It displayed the mountpoint
    under which this path happens to be.

    If I want to find out the free space immediately under the mountpoint,
    I can do 'df mountpoint' or just 'df'. But that's not what the user
    is interested in when it does 'df path', the user is interested in the
    free space under 'path'.

    What is the loss of functionality? For mounts not having
    subfilesystems, there will be _no_change_whatsoever_!

    Why? What if that info is simply not available?

    You are talking about missing functionality not _loss_ of

    Yes, possibility for finding out where subfilesystems are located
    _will_ be missing for such filesystems as sshfs. Is that a reason for
    asuming subfilesystems don't exsist, and not allowing already existing
    tools (filemanagers, openoffice, etc) to make use of a statfs() system
    call which can return _meaningful_ results for subfilesystems?
