Howto prevent the clearing of boot messages (Redhat 6)

I always like to see my boot messages. Well, that’s reason enough.
You have to change one file: /etc/init/tty.conf. Just change the last line, it says:
exec /sbin/mingetty $TTY
and should be changed to be:
exec /sbin/mingetty --noclear $TTY
The --noclear does the trick. For me this is will be the new default setting, at least, when using RH6.

Let me be a little more helpfull, just execute:
sed -i ‘s/\/mingetty /\/mingetty --noclear /g’ /etc/init/tty.conf
