Thanks for clarifying the situation. And I've seen far more /exotic/
configurations! :-[

Oh, I think I remember something about the Ubuntu folks doing some sanity
check on the autostuff, and erroring out in a rather nasty way. I can't
remember what they did either, but they were not entirely wrong, just that
the check was over-conservative...

Unfortunately, I can't remember how that was solved/worked around last time.

Anyway, I don't want that a bug on a system be fixed by introducing another
bug on another system. Let's just *properly fix* it.

Yann E. MORIN.
