# Real nix for the tramiton reproducible-build firmware SBOM.
#
# nix-portable's proot fallback can't run here: user namespaces are blocked by
# the container's default seccomp/apparmor profile, and orca exposes no way to
# relax it. So ship a *real* nix and disable its build sandbox
# (`sandbox = false`) — a plain gcc/make firmware build needs no user namespace,
# so it runs fine under the locked-down profile with no proot involved.
#
# The store is shipped as a bootstrap tarball and seeded onto /nix at first
# start (see docker/agent-entrypoint.sh), so a persistent /nix volume survives
# redeploys. A missing/broken nix just falls back to the analysis-only SBOM.
