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.
