Allocate tty1 for kernel messages

[Dmitry Katsubo <dma_k@mail.ru>]

Dear Debian users,

I am trying to make a following setup on Debian bullseye:

* tty1 is used to display kernel messages only
* tty[2-5] are allocated for login

I have modified /etc/default/console-setup so that it reads:

ACTIVE_CONSOLES="/dev/tty[2-5]"

and rebooted. What I observe is that tty1 displays kernel messages during the boot (OK) but also ends with an invitation for login on tty1 (WRONG).

How can I force that tty1 is not used for login?

Thanks in advance.
