316d38e258 setconsole: much better help text 
Was:

    Redirect system console output to DEVICE (default: /dev/tty)

Now:

    Usage: setconsole [-r] [DEVICE]

    Make writes to /dev/console appear on DEVICE (default: /dev/tty).
    Does not redirect kernel log output or reads from /dev/console.

        -r	Reset: writes to /dev/console go to kernel log tty(s)

ioctl appears to succeed, but kernel's output is not coming
to the specified console (tried on VT consoles too).
