yes, this is *identical* config, I just used a different binary.

If you look careful, you see that it also didn't take the rest of my
options:
  fstype=nfs4,hard,sec=sys,nodev,nosuid,wsize=32768,rsize=32768

So, either I'm not specifying them in a way supported by 5.1.8, or it
somehow doesn't process them and falls back to some defaults.
