[erlang-questions] How to dynamically add one node to erlang's distrubted application?

[Kevin A. Smith]

Would using Erlang's network file loader (erl_prim_loader) in  
combination with one or more boot servers address the problem? This  
would allow you to load code and config from a centralized set of  
servers. You could push dynamic updates out to the nodes while at the  
same time updating the centralized files for any new nodes or nodes  
which have to be restarted.
