Undoing Root "Auto‐Login"

This has been asked several times so I'll list the steps to undo autologin. If you don't set a root password first, you will not be able to login to the container again, ever.

1. set the root password

sudo passwd root

2. Remove Autologin

remove bash--autologin root from bash/etc/systemd/system/container-getty@1.service.d/override.conf

3. Reboot Machine

reboot
