I've tried this and it does not work - the error message is in my first
post. Exporting directories lower than / works fine.

My case might be more complicated: Both machines are exporting filesystems.

The complication is that on A (machine wanting to export root) there
are some directories below / that come from B. But the NFS export
code should handle that right?

Oh well thanks for the suggestions.
