# Build one svc-core binary natively on the development Orin, check it against the
# car's glibc, and install it on the car Orin as the yukart-<bin> service.
#
#   usage: scripts/deploy-native.sh BIN [host]       (host default: mikkeli-orin-nano)
#   env:   BUILD_HOST                                (default: mikkeli-orin-nano-2)
#
# Builds what is pushed, not the working tree: the build host pulls master of
# svc-core and contracts under ~/dev/yukart/. Signal names, units and layouts are
# compiled in from contracts' signals.json, so a registry change needs a redeploy.
# Native because std::process::Command cross-compiled against the workstation's
# newer glibc links GLIBC_2.39 symbols the car cannot load (check-glibc.sh gates it).
#
# A service that reads /etc/default/yukart-elm (the ELM327's address) gets the
# repo's copy installed when the host has none; an existing one is left alone.
