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.

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