NAME

6       kexec  -  Tool  to  load  a  kernel for warm reboot and initiate a warm
7       reboot
8

SYNOPSIS

10       kexec [options] files...
11

DESCRIPTION

13       kexec allows one to load another  kernel  from  the  currently  running
14       Linux kernel. Normally one would load a kernel, and possibly an initial
15       ramdisk, into the currently running kernel using kexec and then  initi‐
16       ate a warm reboot by executing kexec again with appropriate option.
