…t code tonistiigi/binfmt exits 0 even when it fails to mount binfmt_misc and register the emulator - it only logs the error. That let 'setup-qemu' report success while riscv64 support was silently never registered, surfacing as a confusing failure two steps later (e.g. 'cartesi doctor' reporting "Your system does not support riscv64 architecture"). Check /proc/sys/fs/binfmt_misc/qemu-riscv64 directly after running the installer and fail the step with an explanatory message if it's missing. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
