Making a release tar and release is different

[joaohf]

Hello,

Using rebar3 3.14.4 and making a release with:

• rebar3 tar
• rebar3 release

The main problem is because the file bin/erl gets overwrite.

The output will be different. Not sure if this is a regression of this one https://github.com/erlware/relx/pull/70/

The figure below shows the same release. On the left hand side using release and on the right hand side tar:

For completeness, can you provide the configuration you're calling both commands with?

Hmm, I'll investigate it a bit more. The issue seems to be a side effect from my changes related to this one https://github.com/erlang/rebar3/pull/2503.

Anyway, the following shows the commands that I'm using:

rebar3 as prod release -o /tmp/pp --system_libs /home/joaohf/work/opensource/kas-meonrpi/dunfell/build/tmp/work/arm1176jzfshf-vfp-poky-linux-gnueabi/axon/0.1.0-git999-r0/recipe-sysroot/usr/lib/erlang/lib --include-erts /home/joaohf/work/opensource/kas-meonrpi/dunfell/build/tmp/work/arm1176jzfshf-vfp-poky-linux-gnueabi/axon/0.1.0-git999-r0/recipe-sysroot/usr/lib/erlang -n axon

I'm closing this issue for now.

Thanks.
