Erlang VM exited when using -internal_epmd and rebar 3.14

When deploying a GRiSP application with rebar 3.14 the OTP patch to add the -internal_epmd flag (i.e. grisp/otp@5ebbd6a) gets lost in the build process.

When starting GRiSP using internal epmd (e.g. when having wifi configurations as described in the wiki) it results in

Protocol 'inet_tcp': register/listen error: econnrefused
Erlang VM exited

This might be caused by a bug in with the system_libs flag in relx 4.0.0 see erlware/relx#823

Out now: rebar 3.14.2

Is this maybe fixed there? The issue above is close now and its supposed to be fixed here:

erlware/relx#834

So first we need to figure out if this is part of 3.14.2 and if yes figure out that we can fix our problem with this version (possibly not breaking 3.13.x and before if possible)

Not fixed, but with rebar 3.14.2 we now get the error already when we try to deploy the GRiSP application:

$ rebar3 grisp deploy -n robot -v 0.1.0

Hello,

Seems that we have the same issue as described here: erlang/rebar3#2496

Pretty sure this is not an issue in later versions of Rebar (3.16+?) and rebar3_grisp. Closing for now.
