# Assets and packs are moved aside - building them means you find out early if the asset compilation is broken
# not on final deploy. It means that public/assets and public/packs can be volumes in production allowing for
# cached pages / assets to be kept and cleaned the way Rails expects them to be while keeping deployment very fast.
# The assets/packs get copied back by rsync on app load (see ops/nginx.sh)
