1715 | kexec is a system call that implements the ability to shutdown your | |
1716 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 1717 | but it is independent of the system firmware. And like a reboot |
ea6e942b AN |
1718 | you can start any kernel with it, not just Linux. |
