I am trying to build my own Debian 11 live iso and struggling by getting a working getty console output. So far I have figured out that systemd is creating a wrong symlink when enabling the tty1 by using:
systemctl enable [email protected]
It produces the following:
Created symlink /etc/systemd/system/getty.target.wants/[email protected] → /lib/systemd/system/[email protected]
However after enabling the service once again the correct symlink is created, so the faulty one can be removed.
But unfortunately when starting the live iso the [email protected] is permanently restarting and I cannot figure out why. Subsequently I have only a blinking cursor and a black screen. If I follow the workaround and adjust the values within /etc/systemd/system.conf as described here: https://serverfault.com/a/845473 The screen is permanently flickering the status is as follows:
Loaded: loaded (/lib/systemd/system/[email protected]; enabled; vendor preset: enabled)
Drop-In: /run/systemd/generator/[email protected]

I have no idea why this behaves that buggy. Can anyone give me a hint? Basically I follow this tutorial for building the live iso: https://willhaley.com/blog/custom-debian-live-environment/
The GUI mode is working fine but I do not need this in this case. Thanks in advance!
EDIT: Small update. I figured out that within the flickering tty1 console he tries to perform a auto login with the non-existent user "user". So I created the user and now it is logging into this user and the flickering stops. But this is not intended to be so. I only need the root user with non auto-login. I cannot find anything within the default /etc/systemd/system/getty.target.wants/[email protected] which enable the auto-login feature (?)
