The console is directed to ttyS0 via a line in the inittab file.

- /etc/inittab
# Example how to put a getty on a serial line (for a terminal)
T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100
#T1:23:respawn:/sbin/getty -L ttyS1 9600 vt100

So it would be possible to adjust this file after boot once your system
is in a state where you do not need the console.

By the way the command 'init q' will cause init to reload this file.
