The devbox cache is restored to /usr/local/bin/devbox. https://github.com/jetify-com/devbox-install-action/blob/main/action.yml#L58

This works well with github hosted runners. however self hosted runners runs as a runner user and they dont have permission to restore files outside home or workspace.
As a result the cache restore fails.

Various self hosted images are built from Dockerfiles at:

Should the devbox restored and installed at ~/.local/bin directory and make it accessible by adding it to $PATH?
