As you don't expect a server to be in desperate need of new features and new supported hardware I personally don't think that the latest kernel is needed.
What do the others think about it?
No. But what I understood from what Thomas said is: as you need to reboot your server anyway from time to time to apply security updates, you may decide to switch to an even more often updated kernel, if your architecture permit it (reboot != service interruption).
you could try the ksplice route as it's enterprise level quality at this point -- though for arch you'd have to create/apply the splices yourself. i'll be soon attempting this with our gentoo servers (as much as i like arch ... nope :-) manually; for other distros like redhat/ubuntu there is a tool that can apply them from ksplice.com (only the desktop editions are free ... albeit $3-$5/mo/server is pretty decent) the idea is you compile the running kernel and the destination kernel (the patched version w/security updates/etc), then (IIRC) ksplice analyzes the resultant objects, generating a special module that applies a reversible update to the running kernel in real time. pretty neat :-) C Anthony
