Kernel features allows rebootless kernel patching!

This is great! This is a true killer feature. Until now whenever there was a security update for the kernel we had to download the new kernel image, install it and reboot. But on production servers reboot can be a problem.

Apparently this feature existed since 2005 but I just found about it. I even .

and the article that referenced it:

I haven't tried it yet. The problem is that although the kernel and userspace code is GPLed, for the updates you have to pay for (Except for the latest Ubuntu release). So you need the last Ubuntu release to test and and you have to pay for any other release or distro :( . It would be nice if a community emerges to provide this service for free. What do you guys think? That would be a nice project to work on!

Our beloved Oracle has bought Ksplice Inc and they are now monopolizing the technology. Maybe now is a good time for a community to emerge and provide this service for free for major server distros.
