You can also change the /etc/ttys entry from /dev/console to /dev/constty.
/dev/constty is always the console device, but output to it is not
grabbed by the TIOCCONS ioctl.

This is used (by init) in single user mode, and specifically so that
sysinst can intercept writes to /dev/console and then write them out
to the console device without them messing up the curses screen.
