I just installed Debian 9.2.1 on an old laptop as a cheap server. The computer is not physically accessed by anyone other than myself, so I would like to automatically login upon startup so that if I have to use the laptop itself rather than SSH, I don't have to bother logging in. I have no graphical environments installed, so none of those methods would work, and I've tried multiple solutions such as https://superuser.com/questions/969923/automatic-root-login-in-debian-8-0-console-only However all it did was result in no login prompt being given at all... So I reinstalled Debian. What can I do to automatically log in without a graphical environment? Thanks!
/etc/systemd/logind.conf , change
/firstname.lastname@example.org/override.conf through ;
systemctl edit getty@tty1
Past the following lines
[Service] ExecStart= ExecStart=-/sbin/agetty --autologin root --noclear %I 38400 linux
email@example.com then reboot
systemctl enable firstname.lastname@example.org reboot
