.SH SYNOPSIS

|
|
|
|
\fBctrlaltdel\fR [\fB-hs\fR]
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
Based on examination of the linux/kernel/sys.c code, it is clear that
|
|
|
|
|
there are two supported functions that the Ctrl-Alt-Del sequence can
|
|
|
|
|
perform: a hard reset, which immediately reboots the computer without
|
|
|
|
|
calling sync(2) and without any other preparation; and a soft reset,
|
|
|
|
|
which sends 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.
