This looks right.
However, I'm wondering why the 'test -t 1' right after
the exec redirection didn't already catch this:

  if test -w /dev/full && test -c /dev/full; then
  (
    exec >/dev/tty
    test -t 1 || exit 0
    nohup echo hi 2> /dev/full
    test $? = 125 || fail=1
    test -f nohup.out || fail=1
    test -s nohup.out && fail=1
    rm -f nohup.out
    exit $fail
  ) || fail=1
  fi

Does someone have a test log file with the failure?

Have a nice day,
