       You can set this option to `false` to disable the rebooting for applications
       that are sensitive to boot time but, in doing so, note you won't be able
       to configure system applications, such as `:kernel` and `:stdlib`.
+      When set to `true` the computed config file will be written to the "tmp"
+      directory inside the release every time the system boots. You can configure
+      the "tmp" directory by setting the `RELEASE_TMP` environment variable, either
+      explicitly or inside your `releases/RELEASE_VSN/env.sh` (or `env.bat` on Windows).
       Defaults to `true` if using the deprecated `config/releases.exs`,
       `false` otherwise.
 


  If a `config/runtime.exs` exists, it will be copied to your release
  and executed early in the boot process, when only Elixir and Erlang's
  main applications have been started. Once the configuration is loaded,
  the Erlang system will be restarted (within the same Operating System
  process) and the new configuration will take place.

  You can change the path to the runtime configuration file by setting
  `:runtime_config_path` inside each release configuration. This path is


  By setting `:runtime_config_path` to `false` it can be used to prevent
  a runtime configuration file to be included in the release.
