Not initialy no.
They do connect normally once I use connect tho. This works and I can
start up processes on the remote nodes just fine. Both the nodes have
the same cookie in the erlang.cookie file.
Do I understand the expected behavior correctly:
Start node n1 with a boot script that starts (among other things) my
distributed app (erlyhack_map_app). Since the second (preferred) node
is not yet up, it starts up locally.
Start node n2 with the exact same boot script. This attempts to start
the distributed app by first notifying the first node to shut the app
If this is correct, then it must be the node communication that is not
set up correctly during bootup of the nodes.
Is there a way to force the communication to be set up between nodes
after boot that will still cause takeover of distributed apps?

Ah, thanks :)

Once in "single mode" the node will not exhibit any distributed
behavior? Is there a way to check if a node will cooperate in
distributed applications or not?
Thanks for the info. Much appreciated.
