## ---- Nix mutual cache ----
# Let nodes in a same site/zone copy from each other's Nix stores
# Note that nodes will only copy from one another packages that are
# signed by one of the trusted public keys, i.e. packages comming
# from cache.nixos.org and nix.web.deuxfleurs.fr.
# This is good as it kind of mitigates supply-chain attacks where
# one node's cache would become poisonned, although arguably when
# an attacker has gained root access on one node, it can easily
# become root on all the others through Nomad. Downsides include
# missed opportunities for not rebuilding stuff between machines
# (e.g. derivations that are built in the process of doing
# nixos-rebuild), and warnings appearing in the logs whenever such
# an opportunity was not taken due to missing signatures.
