NAME

6       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS

9       ctrlaltdel hard|soft
10

DESCRIPTION

12       Based  on  examination of the linux/kernel/sys.c code, it is clear that
13       there are two supported functions that the  Ctrl-Alt-Del  sequence  can
14       perform:  a  hard reset, which immediately reboots the computer without
15       calling sync(2) and without any other preparation; and  a  soft  reset,
16       which  sends the SIGINT (interrupt) signal to the init process (this is
17       always the process with PID 1).  If this option is  used,  the  init(8)
18       program must support this feature.  Since there are now several init(8)
19       programs in the Linux community, please consult the  documentation  for
20       the version that you are currently using.
21
22       ctrlaltdel is usually used in the /etc/rc.local file.
