Setting `kernel.ctrl-alt-del' to 0 just makes C-A-D send SIGINT to PID 1 (instead of triggering a hard reboot). If you want to make SIGINT trigger a grace shutdown, you can modify the SIGINT handler in the `service/.s6-svscan' directory.
But I personally do not think changing signal semantics (which is already a mess [1]) is the way to go; instead, I recommend using s6-poweroff(8) from s6-linux-init if you are already using that package. If you machine is ACPI-enabled, you can also configure acpid to spawn s6-poweroff(8) when the power button is pressed, so you may push the button to power off your machine.
