[SOLVED] Auto-Login for Root on Local TTY or Password-Free Access

[shalak]

Hello!

I'm looking for a way to enable root auto-login or bypass the password prompt, but only for local TTY (physical monitor and keyboard). It's important that full PAM authentication remains for web GUI and remote access.

Anybody knows the elegant way to achieve this?

Yep, the systemd drop-in unit (followed by systemctl daemon-reload) did the trick:

# cat /etc/systemd/system/getty@.service.d/autologin.conf
[Service]
ExecStart=
ExecStart=-/sbin/agetty --noclear --autologin root %I $TERM

The original unit has ExecStart=-/sbin/agetty -o '-p -- \\u' --noclear - $TERM that replaces 'login' arguments with an option to preserve environment - unfortunately, that doesn't work with autologin, i.e. this is not correct:

ExecStart=-/sbin/agetty -o '-p -- \\u' --noclear --autologin root %I $TERM

So I guess, we're loosing the environment preservation when we enable autologin. I wonder why was it set in a first place?
