Learn - kexec

I read Oracle Linux 6 document. I found about kexec. A kexec is a mechanism of Linux kernel to for fast-boot. I just thought why I had not been interested this feature before. However, it's cool feature, just learn and test. (Note: You can follow each step from Oracle Document)

[root@ol6test ~]# vim /etc/init.d/runkexec
[root@ol6test ~]# chown root:root /etc/init.d/runkexec
[root@ol6test ~]# chmod 755 /etc/init.d/runkexec
[root@ol6test ~]# ln -s /etc/init.d/runkexec /etc/rc1.d/S00kexec
.
.
.
[root@ol6test ~]# service runkexec start
[root@ol6test ~]# sync; umount -a; kexec -e
