"a. Find the line in /etc/inittab that handles
control-alt-delete functionality. It probably looks something like

"ca::ctrlaltdel:/sbin/shutdown -r -t 4 now

sections being delimited by colons) that states the machine should
execute "/sbin/shutdown -r -t 4 now" whenever someone presses the
control-alt-delete key combination (ctrlaltdel in the file)."
