this only concerns secrets which are in a raw file. Some of our
services (e.g. nextclouds) keeps secrets in its database; these remain
untouched.
Not yet deployed because of shitty train internet.
today i woke up to the realisation that there's an extremely obvious way
to make these nicer, & then i did exactly that. For some reason I did
not think of this when originally removing the dependency to nix-hexchen's
evalConfig.
unfortunately, this is not /quite/ a no-op. The only actual change is
different whitespace in some of the semantically-equivalent
coredns-configs that got unified.
