That was a "special" NFS config. Laptops booted from a cd-rom into a basic linux OS and then got all the rest (oracle software, writable components of the OS etc) via NFS mounts to a network appliance (shared) disk box.

The network appliance implementation of NFS apparently has some enhancements to allow this to work without violating the RAC rules. For just playing around, you could probably get away with normal NFS
