[erlang-questions] How does running nodes() on host knows about all connected nodes?

[Christopher Phillips]

    Essentially connecting nodes assumes you want a fully meshed topology,
and is implemented as such. When your main gru node talks to minion1, the
fact minion1 exists is registered (as evidenced by executing nodes() on
gru; vice versa also applies). When gru then establishes connection with
minion2, it communicates the existence of minion1 to minion2, etc. This
can, as indicated, be disabled with connect_all being set to false, but
that also prevents global registration of processes. You can also set the
minion nodes to be hidden nodes; this changes some of the semantics
necessary to interact with them.
