#
# Builds the aardvark-dns .txz package from upstream source (Rust).
# aardvark-dns provides container-to-container DNS name resolution within
# netavark-managed networks (see docs/ARCHITECTURE.md section 8). Installed
# as a libexec helper binary, same rationale as netavark.
#
# Requires (in the build environment): rustc, cargo.
