How to add db node dynamicaly

[Samuel Tardieu]

| Start mnesia on the new node as a ram node (without a schema on disc)
| and invoke mnesia:change_config(extra_db_nodes, [a@REDACTED, b@REDACTED]) on 
| the node.

I just learned something, thanks. Maybe the doc should be state explicitely
that this can be run on the new node (I may have missed it though).
I thought that it could only be done on a node with the "real" mnesia
started already, and I was using:

  rpc:call (a@REDACTED, mnesia, change_config, [extra_db_nodes, [node()]])
