           kexec is a system call that implements the ability to shutdown your
           current kernel, and to start another kernel.  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 similiarity to the exec system call.
