Slice 1 / PR3 (the cutover fix) of moving the nix builder onto podman.
During the live cutover I found the container's nix couldn't verify TLS to cache.nixos.org from the remote-build ssh session (it doesn't inherit the image
SSL_CERT_FILEenv) → it built every dep from source. Fix: setssl-cert-filein the container's nix.conf (read regardless of env) + re-pinNIX_BUILDER_IMAGEto the fixed digest (@sha256:826d67c0…).Verified live: with Lima stopped, the host nix daemon offloads a real OCI build (
nix build .#packages.aarch64-linux.dolt-box, EXIT=0) to thenix-buildercontainer — root→container ssh, substitution, and a deterministic build all work. (The dolt-data FOD hash-mismatches across builders —dolt cloneisn't byte-reproducible — a separate Phase-2 note, not a builder issue.)The live container + the host-side
/etc/nix/machinesregistration are in place; removing the Lima builder line is the final operator (sudo) step.🤖 Generated with Claude Code
