It is like a reboot but it is independent of the system firmware. And like a reboot you can start any kernel with it, not just Linux. The name comes from the similarity to the exec system call. It is an ongoing process to be certain the hardware in a machine is properly shutdown, so do not be surprised if this code does not initially work for you. As of this writing the exact hardware interface is strongly in flux, so no good recommendation can be made. config BOOTINFO_PROC bool "Export bootinfo in procfs" depends on KEXEC && M68KCLASSIC help Say Y to export the bootinfo used to boot the kernel in a "bootinfo" file in procfs.
