    At least one of the sections is well-deserved: umapfs is horribly broken on
    -current, and only works by accident on previous releases. I'm actually
    considering putting an even stronger warning on that one. The others (null and
    union) aren't nearly as bad, and have been fixed significantly since the
    notice was put on the manpages.
