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.

122 "bootinfo" file in procfs. This is useful with kexec.
