is there a way to cause the nodes to come up using a specific

You can do 'erl -sname node@REDACTED' on node1

or better yet, is there a better way for the master to find

the nodes check in when they come up,

I guess you'd need some kind of discovery protocol. Maybe the slaves can
broadcast a 'is there a master' message periodically until they find one?
The master could also broadcast a message when it is up so that slaves
receive it and register themselves.
