# apt-cacher-ng config for the elizaOS Live containerized build.
#
# Derived from Tails' vagrant/provision/assets/acng.conf. Tails runs
# apt-cacher-ng *inside* its build VM for a specific reason, not just
# speed: a Tails chroot hook sets the chroot's /etc/apt/resolv.conf to
# "nameserver 127.0.0.1" (the final system resolves DNS through Tor).
# At build time there is no Tor, so the chroot cannot resolve hostnames
# — and later hooks still run `apt-get install` inside that chroot.
# Pointing apt at a proxy by IP (127.0.0.1:3142) sidesteps chroot DNS
# entirely: the proxy runs in the container, where DNS works, and does
# the real fetching. We replicate that, container-side.
#
# As a bonus the package cache (a Docker named volume) persists across
# builds, so re-builds skip the network — Tails' other reason for acng.
