Patch your live Linux kernel without reboot

Now this is a remarkable piece of technology. Ksplice allows you to patch a running Linux kernel without the need to reboot your system. Of course there are restrictions. The patch should not introduce semantic changes to kernel datastructures. Now this is not really a restriction since most security patches won’t change the kernel datastructures and this technique is typically used to apply security patches to running systems. ZDnet also reports on Ksplice.

When I have the time I will definitely play around with this software.
