.Sh DESCRIPTION
|
|
Based on examination of the
|
|
.Pa 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
|
|
.Xr 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
|
|
.Xr init 8
|
|
program must support this feature.
|
