The system user was removed from all install scripts but the OpenRC init script still referenced linux-patch-api:linux-patch-api in checkpath. This would cause the service to fail on Alpine because the user does not exist.
- Updated SPEC.md: Changed systemd requirements to distribution-dependent init system - Updated ARCHITECTURE.md: Added OpenRC hardening options and init script locations - Updated build-alpine.sh: Replaced systemd-dev with openrc, use /etc/init.d - Created configs/linux-patch-api-openrc: Full OpenRC init script - Added Dockerfile.rpm for RPM build container Init system support: - systemd: Debian, Ubuntu, RHEL, CentOS, Fedora - OpenRC: Alpine Linux Binary remains init-system agnostic - no Rust code changes required.
