| 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. |
