commit 79d28b8e5305e6bbfd1a30328a929434b199d207

    Create /dev/tty because 'rinse' doesn't
    
    Test case:
      echo Hello >/dev/tty
    Expected:
      ls -l /dev/tty
      crw-rw-rw- 1 root tty 5, 0 Jun  2 13:32 /dev/tty
    Observed:
      -rw-rw-r-- 1 root root 6 Jun  2 13:55 /dev/tty
    because "Hello\n" contains six characters. Side effect: after root has
    written to /dev/tty , normal users cannot. This goofy workaround:
      echo Hello | sudo tee /dev/tty
    yielded a return code of zero, so it "succeeded" in that sense, but it
    didn't write anything to the TTY. Diagnosis: the special device didn't
    exist, so writing to /dev/tty was like writing to /dev/xyzzy .
