[LUG] Swap Kernel Without Reboot

 

Interesting article for all the server administrators out there (and
probably anyone else).

http://it.toolbox.com/blogs/locutus/the-end-of-physical-reboots-with-linux-27137

Use kexec to update the kernel (or just change it to a different one)
without having to physically reboot the system. All applications and
connections will be closed, but they'll start back up a lot quicker
than a server boot would take (only really important if you're either
an uptime junkie, or second matter to your business.)

Still, and interesting article all the same.
