In the times of yore, it was enough to edit /etc/inittab and comment the relevant line there.
Now that systemd has taken over, the information about disabling this appears to be behind a paywal in RedHat's support web site: https://access.redhat.com/solutions/1123873
Other information which can be found on the Intertubes talks about running:
Code: Select all
# systemctl mask ctrl-alt-delete.target
# systemctl daemon-reload
However, I run those those commands and still Ctrl-Alt-Delete is rebooting my test system.
Anyone has any insights about that?
