## Build a Nix derivation without binary cache substitution

# Use a separate, temporary Nix store, so we can debug derivations that are already
# available in the main store
store="--store /tmp/store"
sudo rm -rf /tmp/store

# Fetch all build deps from the binary cache
nix print-dev-env $store --substitute myflake#output >/dev/null

The basic recipe for deploying a nix-bitcoin VM

• Create a new nix-bitcoin node config
• Deploy the packer NixOS base image
• Deploy the nix-bitcoin node config.
  You should use a NixOS deployment method that includes local building.
  In this way, common build components are cached on your main dev system so that new nodes can be built very quickly.
  One possible method:
  • Add nix-bitcoin.setupSecrets = true; to the node config
• For deploying:
