ctrlaltdel - set the function of the Ctrl-Alt-Del combination
== SYNOPSIS
*ctrlaltdel* *hard*|*soft*
== DESCRIPTION
Based on examination of the _linux/kernel/reboot.c_ code, it is clear that there are two supported functions that the <Ctrl-Alt-Del> sequence can perform.
Make the kernel send the *SIGINT* (interrupt) signal to the *init* process (this is always the process with PID 1). If this option is used, the *init*(8) program must support this feature. Since there are now several *init*(8) programs in the Linux community, please consult the documentation for the version that you are currently using.
