‘Node’ images are just minimal CentOS plus all the packages for this release, in a sub-DVD sized ISO. Once it is installed, the operating system is still CentOS, and can be patched/modified, including installing alternative kernels. If it fails, boot back to the original kernel, and remove the package from Elrepo, or at worse, re-install.

What would be the easiest way to have a 5.x kernel on this node? I don't mind compiling if it needs to. Cheers, Shantur
