If you want to completely isolate apt from the system configuration for apt, the correct way to do that is to set the APT_CONFIG environment variable. See apt.conf(5), APT_CONFIG is the first mechanism used for setting the apt config and /etc is the second place apt looks for configuration. If you do not want to override every item (including hooks/etc) in every file in /etc/apt/apt.conf.d then you need to use APT_CONFIG. Examples of how to do this include chdist (from devscripts), apt-venv or the derivatives census codebase. -- bye, pabs https://wiki.debian.org/PaulWise
