Ghost init doesn't retrieve stash path from os environ

[Coder-DG]

OS environment variables are completely ignored when using ghost init.

This was actually done on purpose as providing a path for a stash should be either explicit or default. For instance, you might already have a stash initialized and have the environment variable set on a previous stash. Now, when running ghost init, you would try and initialize an already existing stash. I'm closing this.
