        safe_mkdir() fixed (don't create .../dev if mounted)
        check_chuser() fixed (-z "${var}" instead of -z ${var})
        setup_umask() fixed (dhcpd_umask -> dhcpd_withumask)
        dhcpd_stop() fixed (sh $0 force... instead of $0 ...)
        _dhcpd__uninstall() added
        dhcpd_uninstall() recursively called to handle all the
        combinations of dhcpd_chuser_enable and dhcpd_chroot_enable
