Console getty respawns and crashes.

An error was reported in log files (var/log/).

In particulare in “messages”:

May 30 11:54:41 xxx00962 systemd: Starting Serial Getty on ttyS0...
May 30 11:54:41 xxx00962 systemd: Started Serial Getty on ttyS0.  
May 30 11:54:51 xxx00962 systemd: serial-getty@ttyS0.service holdoff time over, scheduling restart.
May 30 11:54:51 xxx00962 systemd: Stopping Serial Getty on ttyS0...

in “secure”:

May 30 15:51:30 xxx00962 agetty[24693]: /dev/ttyS0: not a character device

where xxx00962 is the hostname.

Solution

Currently the proposed changes to the templates from images.linuxcontainers.org don’t seem to be implemented. It took me an embarrassingly long time to find the correct commands to disable getty.

systemctl stop console-getty
systemctl disable console-getty
systemctl mask console-getty

If you don’t mask, console-getty will be automatically enabled on the next boot.
