506 kexec is a system call that implements the ability to shutdown your
507 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400508 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800509 you can start any kernel with it, not just Linux.
510
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400511 The name comes from the similarity to the exec system call.
