No More Need To Reboot Fedora w/ Ksplice
An anonymous reader writes "Ksplice, the technology that allows Linux kernel updates without a reboot, is now free for users of the Fedora distribution. Using Ksplice is like 'replacing your car's engine while speeding down the highway,' and it can potentially save your Linux systems from a lot of downtime. Since Fedora users often live on the bleeding edge of Linux development, Ksplice makes it even easier to do so, and without reboots!"
When you have around 1500 production servers to patch, such as with the memmap 0 bug last year, doing them one-by-one, or even in small batches, remotely over IP KVM takes a long-ass time. This is nice for those types of situations.
Seriously? I patched 5500 linux servers in 24 hours *by myself*, all the while they were churning through collider data from the LHC. This would be, in my opinion, what I would call a production environment. Shortcuts are nice, but sometimes you don't need them if your environment is engineered properly.
