[Howto]Make CtrlAltDel poweroff not reboot

[pepedog]

Code: Select all

ln -sf /usr/lib/systemd/system/poweroff.target /etc/systemd/system/ctrl-alt-del.target

That's it, attached USB keyboard CtrlAltDel now powers off instead of reboot

I count on CTL-ALT-DEL to enable me to reboot when keyboard commands are not recognized, but CTL-ALT-DEL is. Hope that change will not become part of the firmware?

It won't.
I know you run headless but I was thinking of other headless uses.
Or yourself in earlier rpi days where you wanted to examine logs cleanly shut down

Not sure I completely understand, right now I need to BOTH poweroff safely and reboot. I am nervous about having to frequently reboot with CTL-ALT-DEL without syncing first, but no choice, it is still better than poweroff. We are supposed to sync before poweroff, aren't we? Still having these issues, but at least no longer having to constantly reflash an image.

Nice. Thanks for that
I was tinkering with this under Kali for RPi.

Code: Select all

ctrl-alt-del = poweroff
ln -sf /usr/lib/systemd/user/exit.target /etc/systemd/system/ctrl-alt-del.target
