Looks like the mount definitions require the :ro (or maybe :rq?) at the end unlike regular docker volumes, that was the issue.

What’s required to map a folder into one of the containers (i.e. retroarch)? I’ve attempted to edit config.toml to include it, but the main wolf container immediately crashes on boot due to interrupt code 11. There’s no other error messages, just a binary stack trace.

The folder exists. I’ve tried directly mounting the host path as well as mounting it into Wolf-Wolf-1 and using the local path, but nothing works. Even perfectly mirrored paths don’t work. Wolf appears to be running as root so I don’t think it’s a permissions error? I can certainly access the folders. They are a locally mounted NFS, but I’ve used this with dozens of containers without issue.
