Hello,

I have explained. You have NOT understood what I said. I explained what
the linux console is - it is has NOTHING to do with user logins!!! The
kernel has absolutely no knowledge of how a user "logs in" - that is all
handled in user space.

You are right, but that doesn't help much here. If you use a serial
console, you most probably will start some getty-process or simply a shell
on it. But,whether you do or nor, the kernel will print onto this console,
too, and his question is simply:

"How can I completely disable / redirect the console after booting?" (If
I'm wrong here, then please correct me. This is what I understood.)

You have to see it in context - it is about getty processes and whatever,
but also the kernel messages are important.


just picked up on this thread so maybe this was covered. To redirect the
device that the kernel believes is the console use a kernel command line
parameter like console=/dev/null. I use my serial console port to control
a robotic arm so I cannot have kernel messages interfering with my arm
control.
