| 451 | help |
| 452 | kexec is a system call that implements the ability to shutdown your |
| 453 | current kernel, and to start another kernel. It is like a reboot |
| 454 | but it is indepedent of the system firmware. And like a reboot |
| 455 | you can start any kernel with it, not just Linux. |
| 456 | |
| 457 | The name comes from the similiarity to the exec system call. |

| 459 | It is an ongoing process to be certain the hardware in a machine |
| 460 | is properly shutdown, so do not be surprised if this code does not |
| 461 | initially work for you. It may help to enable device hotplugging |
