Currently Linux kernel with CONFIG_NUMA on a system with multiple possible nodes, marks node 0 as online at boot. However in practice, there are systems which have node 0 as memoryless and cpuless.
Would it not be better and simpler to require that node 0 always has
memory (and processors)? A mininum operational set?
We can dynamically number the nodes right? So just make sure that the
firmware properly creates memory on node 0?
