I'm eagerly awaiting the deployment of a dedicated server, but it will be running version 2.2.22 of the Linux Kernel (I believe that's the vanilla release version with Debian 3r2).
I've only ever used a VPS before in a hosting environment. In general, how do kernel upgrades go in a dedicated hosting environment? In particular, I'm looking to move to the latest stable 2.4.x kernel (2.4.26 I believe).
Cool, I'm ok rebuilding the kernel and I'll build a VMWare machine as close to possible to run through the upgrade, I'm just worried about what happens if there are problems during the boot, requiring me to get someone to go in and sort it out.
Anyway, I'll speak to the hosts and see what they say, just wondered if there was a norm and what it was
If you're concerned whether it'll come back up with no issue, how's about building the kernel, installing and then requesting the DC do a reboot, then can than reboot it for you on the default kernel if the new one fails.
Unless you have KVM over IP, then you'll have to get the tech in the DC to do the 2nd reboot if it fails to boot OK. If you can get them to do the initial reboot, they'll (hopefully) wait about until it's completed it's boot and if instructed beforehand I guess most will reboot it and select a default kernel for you. Less downtime if you don't come back up after the reboot.
