it would be nice if things were that simple. your idea only works if
no failures happen. (lots of things are simple if no failure happens.
code paths become nice and clean.) since we would like to deal with
failures, things are a bit more complicated. at the heart of it is a
reconfiguration request that gets committed using Zab.
