One part of releasing Elixir applications I never found a definite answer was how closely the build environment has to match the final environment where the release is deployed. The Erlang runtime is bundled with a release, and this part is platform-dependent as far as I understand.

If I'm writing an application that I'll only deploy myself I can of course match the environments exactly. But what about if I wanted to distribute an Elixir application to end users that might install it on all kinds of different operating systems and distributions? Do I have to build a release for OS/architecture combinations like Linux/64bit, Windows/32bit and similar? Or do I have to match each Linux distribution and windows version exactly? That would make it rather impractical to use Elixir to write software you give to other people, and don't deploy yourself.

Of course when I looked at this Distillery was the standard way to deploy, but it doesn't look like this part is any different with Elixir Releases.
