Mounting /root/.cache from Docker image? Override model cache path?

[bioshazard]

I found that models for eg Bark were downloading to /root/.cache/ and would have to re-download if I changed the docker compose YAML because that file path was in the ephemeral container overlay. Are there recommended patterns for avoiding re-download when the ephemeral disk is lost? I tried to mount /root/.cache/huggingface to a folder on the host but got inconsistent results.
