# 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.
