    /dev/console is probably unsuitable for this (/dev/console is an
    interactive device), but something like /dev/kmsg would probably be a
    good idea -- it can also replace /proc/kmsg.

    However, Andrew's sys_syslog() change does what I need, since users are
    used to calling syslog(3) to log messages anyway.
