For the authentication session identifier, we're currently using Application.compile_env. Check how this relates to the configuration in dev.exs and if it's the correct way to read configuration from there.

Although the elixir docs recommend to use runtime configuration by default, in this case I think compile-time configuration works better because the configuration should

never change
be set before the application starts

I did a small adjustment in a3746dfaaa - otherwise, this works well the way it is.

One extra confusing thing is that there are two environments in elixir:

the "Application environment" configured in config.exs
Standard linux environment variables, read via System.get_env
