ctrlaltdel — set the function of the Ctrl-Alt-Del combination
ctrlaltdel
hard | soft
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. Since there are now several init(8) programs in the Linux
community, please consult the documentation for the version
that you are currently using.
ctrlaltdel
is usually used in the /etc/rc.local
file.
