Description
I've found the following issue in Fileserver with Proxmox LXC.
The container-getty service restarts every minute and spams the syslog in an endless loop.
To reproduce:
- install
debian-12-turnkey-fileserver_18.0-1_amd64.tar.gzin Proxmox LXC - finish the initial config
- reboot the container
- wait a few minutes and check the syslog with
journalctl -e:

The default agetty process is changed by the inithook from
-/sbin/agetty -o '-p -- \\u' --noclear - $TERM
to
-/sbin/agetty -n -l /bin/bash -o "/usr/lib/inithooks/bin/login_script.sh" --noclear --keep-baud pts/%I 115200,38400,9600 $TERM
The service is defined with Restart=always so as soon as the process finishes, systemd restarts the service.
The login_script.sh calls the login program.
root@filetest ~# cat /usr/lib/inithooks/bin/login_script.sh
#!/bin/bash
. /etc/default/inithooks
${INITHOOKS_PATH}/run
clear
echo -en "\nDebian GNU/Linux $(lsb_release -rs) $(hostname) tty1\n\n"
login -p
The login waits for LOGIN_TIMEOUT seconds defined in /etc/login.defs.
#
# Max time in seconds for login
#
LOGIN_TIMEOUT 60
After 60 seconds, the login process exits, and the sytemd restarts the service. And it is happening forever while the container is running.
