| .SH NAME |
| ctrlaltdel \- set the function of the Ctrl-Alt-Del combination |
| .SH SYNOPSIS |
| .BR "ctrlaltdel hard" | soft |
| .SH DESCRIPTION |
| Based on examination of the |
| .I linux/kernel/sys.c |
| code, it is clear that there are two supported functions that the |
| Ctrl-Alt-Del sequence can perform: a |
| .I hard |
| reset, which immediately reboots the computer without calling |
| .BR sync (2) |
| and without any other preparation; and a |
| .I soft |
| reset, which sends the SIGINT (interrupt) signal to the |
| .B init |
| process (this is always the process with PID 1). If this option is used, |
| the |
| .BR init (8) |
| program must support this feature. Since there are now several |
| .BR init (8) |
| programs in the Linux community, please consult the documentation for the |
| version that you are currently using. |
| |
| .B ctrlaltdel |
| is usually used in the |
| .I /etc/rc.local |
| file. |
