Changes to Common Runtime handling of $HOME directory when running container images

Change effective on 24 August 2021

Previously the Common Runtime would overwrite the $HOME env var with the value / when running container images. We’re rolling out a change to the Common Runtime to no longer overwrite this environment variable which will bring the Common Runtime container support in line with Private Spaces and with other container runtimes.

If your Heroku app has come to rely on the previous behavior you set a config var to get the previous behavior:

$ heroku config:set HOME=/
