Hi all, I'm not very used to CentOS and Linux generally speaking, though I read a lot and 'man' quickly became a very good friend of mine, right after Google, so sorry if that's a ridiculous one! (at least it'll give you a good laugh!) I updated the kernel to 2.6.9-42.0.2 recently and that raised a question... Simple... Yet silly...! What exactly is the difference between 2.6.9-42.0.2EL and 2.6.9-42.0.2ELsmp? It seems the default install was the 'smp' kernel, but as I had to change the grub config I stumbled across this one and... started wondering...

The default EL kernel is for a single processor system, but is installed as a failsafe kernel on smp systems "just in case". -- During times of universal deceit, telling the truth becomes a revolutionary act.
