relx-on-windows

I have had issues getting rebar3 releases / relx to work on Windows.

So this respository is a container for my notes and the apps used for testing.

Sample applications

Two sample applications, rebar-app and relx-app, have been made for testing the rebar and relx commands.

Issue 1 relates to the generation and renaming of configuration files (sys.config and vm.args) with the .orig extension.

Issue 2 relates to erts path discovery on Windows.

Issue 3 relates to modifications of the system installed erlang file erl.ini being Access is denied.

Issue 4 relates to the correct symlinks being created for files vs folders.

Issue 5 relates to the $ERTS_LIB_DIR boot variable not being provided by the windows management scripts.

Issue 4 - In my opinion, hard links are not visible on Windows through the command line or Windows explorer.

For this reason I would suggest fix option 1 as the best option. NOTE: Avoiding the issue and using symbolic links gives the best visibility.
The code in Issue 4 may need to be revised in future issues relating to the re-creation of a release and associated symlinks.

The two future issues are:
1. Re-creating a symlink results in a aleady exists error.
2. Ignoring the already exists error when the {vm_args, _} configuration has changed may result in a stale link to the wrong file.
