help |
|
kexec is a system call that implements the ability to shutdown your |
|
current kernel, and to start another kernel. It is like a reboot |
|
but it is independent of the system firmware. And like a reboot |
|
you can start any kernel with it, not just Linux. |
|
|
|
The name comes from the similarity to the exec system call. |
|
|
|
It is an ongoing process to be certain the hardware in a machine |
|
is properly shutdown, so do not be surprised if this code does not |
|
initially work for you. As of this writing the exact hardware |
|
interface is strongly in flux, so no good recommendation can be |
|
made. |

Say Y to export the bootinfo used to boot the kernel in a |
|
"bootinfo" file in procfs. This is useful with kexec. |
