# OPTIONAL internal package cache, e.g. --build-arg PKG_CACHE=https://192.168.1.40
# (CT130 pkg-cache, https only). Unset = upstream repositories. epel-release is
# GPG-verified against keys/pkg-cache/ either way. Repo files are restored at
# the end of the RUN, so no layer keeps the cache address. Same script as
# cloud-apache-container (scripts/pkg-cache-repos.sh, docs/pkg-cache.md there).
