How'd you like to never have to reboot a Linux box again -- no, not even if you have to apply a kernel-level patch? That's the promise of Ksplice, a software technology for Linux (and maybe soon other platforms) designed to allow a system to be patched from the kernel level on up without having to be restarted. It's available right now for Ubuntu, and from what I can see, it's not digital snake oil.

The idea may seem complicated, but the implementation isn't.
