# Binary cache configuration.

# Substituters and trusted public keys for cache.nixos.org and
|
|
# nix-community, plus a stub for the aiolabs cache (uncomment when
|
|
# configured). Imported by every host that wants pre-built artifacts
|
|
# instead of compiling from source.
|
|
#
|
|
# Why this exists as its own module: the optimize-deploys/unified flake
|
|
# notes that host1/host3/host2 share ~90% of derivations, so the second
|
|
# and third deploys would be near-instant once a cache is set up. Same
|
|
# applies for the dev box rebuilds. Rather than scatter substituter
|
|
# configuration across every host, define it once.
|
|
#
|
|
# Pushing to the cache is one Makefile target (`make cache`) — see the
|
|
# top-level Makefile.
