In the not-too distant past, one could disable Ctl-Alt-DEL. Can't do it anymore.

Observe that reboot() returns 0 and `strace` understands what parameters were passed. The result is that, if I hit Ctl-Alt-Del, `init` will still execute the shutdown-order (INIT 0).
A side note, while researching this problem, I think I found that LINUX_REBOOT_MAGIC2 is Linus' birthday (in hex). Maybe the problem is that he no longer observes his birthday?
