Sorry Michael - it was at the end of infinitely many searches and I didn't make 
a note of it.

...but today I see, buried in what you might call the small print: "If the NFS

(e.g. /export/home or /export/data) needs to be specified when mounting." [1]

We could debate whether that's guidance enough.
