503 | kexec is a system call that implements the ability to shutdown your |
504 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 505 | but it is independent of the system firmware. And like a reboot |
cad82448 PM |
506 | you can start any kernel with it, not just Linux. |
