8 | .SH DESCRIPTION |
9 | Based on examination of the | |
6e82b1f3 | 10 | .I linux/kernel/reboot.c |
6dbe3af9 | 11 | code, it is clear that there are two supported functions that the |
6e82b1f3 SK |
12 | Ctrl-Alt-Del sequence can perform. |
13 | .TP | |
14 | .B hard | |
15 | Immediately reboot the computer without calling | |
8cd1bc97 | 16 | .BR sync (2) |
6e82b1f3 SK |
17 | and without any other preparation. This is the default. |
18 | .TP | |
19 | .B soft | |
c3cd6751 | 20 | Make the kernel send the SIGINT (interrupt) signal to the |
6dbe3af9 KZ |
21 | .B init |
22 | process (this is always the process with PID 1). If this option is used, | |
23 | the | |
8cd1bc97 | 24 | .BR init (8) |
6dbe3af9 | 25 | program must support this feature. Since there are now several |
8cd1bc97 | 26 | .BR init (8) |
6dbe3af9 KZ |
27 | programs in the Linux community, please consult the documentation for the |
28 | version that you are currently using. | |
