273 | kexec is a system call that implements the ability to shutdown your | |
274 | current kernel, and to start another kernel. It is like a reboot | |
275 | but it is independent of the system firmware. And like a reboot | |
276 | you can start any kernel with it, not just Linux. | |
277 | ||
278 | The name comes from the similarity to the exec system call. | |
279 | ||
280 | It is an ongoing process to be certain the hardware in a machine | |
281 | is properly shutdown, so do not be surprised if this code does not | |
282 | initially work for you. It may help to enable device hotplugging | |

576 | This option will enable prompting for a variety of advanced kernel | |
577 | configuration options. These options can cause the kernel to not | |
578 | work if they are set incorrectly, but can be used to optimize certain | |
579 | aspects of kernel memory management. | |
