IEx.configure doesn't work in release
I was trying to customize iex prompt so that it will show different env name(by reading it from system env) in release mode. The purpose is to alert myself that I am interacting with a shell in one env(so that it’s harder to mistake production shell as staging shell).
However it looks like IEx.configure has no effect in remote console. I wonder if someone know what’s reason? And is there other workaround to do the customize prompt thing in release?
Thank you very much.

Remote consoles are fun in that your prompt is on a local instance but the process executing what you type is remote. So, you might be configuring the wrong prompt. It might work to take self/0 (the process executing what you type), run it through Process.group_leader/1, take its node, then RPC a call to IEx.configure there. Pretty does this in reverse to get your local console’s inspection settings. It’s something like this:
Process.group_leader()
|> :erlang.node()
|> :rpc.call(IEx.Config, :inspect_opts, [])

I was trying to do exactly the same by putting the following in my runtime.exs
config :iex, default_prompt: "#{System.get_env("RENDER_SERVICE_NAME")} > "
But these settings are ignored when connecting to my release with remote command.
Found any solution?
