Porcelain with destillary

[eidge]

Hello I'm trying to produce a release with distillery with goon bundle in the release itself.

Since one can't use :code.priv_dir(:app) in config.exs, I tried adding this to my application bootstrap code:

Application.put_env(:porcelain, :goon_driver_path, Path.join(:code.priv_dir(:app), 'goon'))
:ok = Porcelain.reinit(:goon)

I've checked the correct path is being generated, but porcelain still complains it can't find goon.

Any ideas on how to solve this? Or any other strategy for bundling goon in the release itself?
