Linux One of the problem with operating system updates is that you often need to reboot the system. While this is nothing but a minor nuisance for us desktop users, it's a bigger problem when it comes to servers. Ksplice is a technology that allows Linux kernel patches to be applied without actually restarting the kernel.

RE: What's wrong with a reboot?

That is correct. What kind of service is so important that it needs to be always up, yet not important enough to justify a failover scheme?

Projects like this are nice, of course. But they aren't practical at all.

Because some things are really hard (or just expensive) to be able to complete failover for, like Linux with specific hardware for running telephony systems.

Even 0.02 cents per machine could be to expensive if their are a lot of machines. For example it would be really nice if the update of your cable-modem didn't disconnect you from internet for a couple of minutes.

For some things it's just easier on the administrative side, like the cluster running calculations where you don't want to move jobs around and rebooting cluster-nodes that haven't been rebooted and then moving the jobs back and rebooting other nodes and keeping track of which you have and haven't had.

Their could be many reasons. :-)
