[erlang-questions] Erlang OTP .rel file start/supervise application remote node

[db]

Here is my answer to my own question:

> Does erlang otp and .rel files allow starting/supervising application on
> remote node?

OTP does not support this feature in application level or in process
level where supervisor on a different node and process on remote node.

Erlang OTP module supervisor only able to supervise(start/stop/
monitor) process on the same node.  Note, there is no supervisor
support for process on remote node.
