103 | help |
104 | kexec is a system call that implements the ability to shutdown your | |
105 | current kernel, and to start another kernel. It is like a reboot | |
106 | but it is independent of the system firmware. And like a reboot | |
107 | you can start any kernel with it, not just Linux. | |
108 | ||
109 | The name comes from the similarity to the exec system call. | |
110 | ||
111 | It is an ongoing process to be certain the hardware in a machine | |
112 | is properly shutdown, so do not be surprised if this code does not | |
113 | initially work for you. As of this writing the exact hardware | |
114 | interface is strongly in flux, so no good recommendation can be | |
115 | made. | |
