Hmm... i assumed wrongly then. i thought the reason for the -linode kernels was that they were required.
They're convenient. They're automatically the latest approved kernel from Linode, so a simple reboot is often enough to get you the latest approved kernel. They've got a configuration set that's optimally compatible with linodes (although mistakes have been known to be made). It's a "set it and forget it" kind of thing.
You can, however, load whichever kernel you want by selecting the pv-grub option. When that's selected, Xen will boot your linode with whichever the default kernel you've configured grub to use.
Some people on linode even use ksplice to get kernel updates without rebooting, although I don't know what the situation with ksplice is after they were bought out by Oracle. They seem to still be offering service for Ubuntu and Fedora, but have dropped support for everything else, and it may only be a matter of time before everything but Oracle Linux gets dropped.
