Reip is the old, evil way to do it that is fraught with peril. When it works it works spectacularly, and when it doesn't, it fails spectacularly. The only use case left for reip is when you have simultaneously changed the node name for every node in the cluster, such as when loading an entire cluster's worth of backups to new machines. Since a node will not be able to start unless it is a member of the ring it currently holds, and `riak-admin cluster [force-]replace` requires there to be at least one node in the cluster running, reip is the only option to get the first node started. After the first node, all the rest can be handled with cluster replace.

Huh. I thought we were supposed to use "force-replace" instead of "reip"? I remember having a discussion a few months back about the documentation and we cleared it up a little. Is "reip" the same as "force-replace", or is it more..."quick-and-dirty?" Is it deprecated? -B.
