# container

# This step is required because of the way docker/bash.sh works. It sets the user home directory to
# /workspace (or the TVM root, anyhow), and this means that zephyr expects a ~/.cache directory to be
# present *in the TVM project root*. Since we don't intend to add one to avoid dirtying the repo
# tree, we need to populate the zephyr fallback cache directory and ensure it's writable. Cache
# artifacts aren't intended to be saved into the docker image.
