I isagree with the statement that we _can't have_ redundant
environments in a file system. It may not be supported by the
current implementation, but there is actually nothing that would
prevent us to come up with more powerful code that supports exactly
such a feature.
[This does not mean that I disagree with your patch - on contary, I
think it's good.]
Best regards,
