This problem comes up often.

You can NOT use /dev/console as your interactive login device without
first calling the ioctl to make it a "controlling tty".  (Sorry I don't
have which ioctl handy.)

The correct thing to do is use the serial port, or virtual TTY as your
console device.. i.e.:

/bin/sh < /dev/console > /dev/console   is _WRONG_.  It works for
testing, but you don't have a controlling terminal.

You need to do something like:

/bin/sh < /dev/ttyS0 > /dev/ttyS0

(and if you want to see error messages, redirect that as well)  :)
