92 | help |
93 | kexec is a system call that implements the ability to shutdown your | |
94 | current kernel, and to start another kernel. It is like a reboot | |
95 | but it is independent of the system firmware. And like a reboot | |
96 | you can start any kernel with it, not just Linux. | |
97 | ||
98 | The name comes from the similarity to the exec system call. | |
99 | ||
100 | It is an ongoing process to be certain the hardware in a machine | |
101 | is properly shutdown, so do not be surprised if this code does not | |
102 | initially work for you. As of this writing the exact hardware | |
103 | interface is strongly in flux, so no good recommendation can be | |
104 | made. | |
