Remove magic button ctrl-alt-del

[jnieuw]

This has already been answered for an old version of Proxmox. How can this be done on a newer (5.x) version?

PVE 5.x is using systemd as init-system - according to the docs: https://www.freedesktop.org/software/systemd/man/systemd.special.html
you want to change `ctrl-alt-del.target`.
Without testing it - I guess `systemctl mask ctrl-alt-del.target` should work and do what you want

Thank you. Your guess was right:

systemctl mask ctrl-alt-del.target
Created symlink /etc/systemd/system/ctrl-alt-del.target → /dev/null.

Problem was CTRL+ALT+DELETE could also be pressed (and rebooting the server) in the login screen. This fixed it.
