    Manual page bug: two inaccuracies in nfsd(7)
    
    Here is a patch that deletes the mention of auth.domain and changes the
    wording around 'flush' files. I'm not attached to the revised wording;
    it's just the best I could manage in something that felt that it was
    within the same style and space as the current wording.
