• Partitioning a new disk non-interactively without writing to the wrong device

  parted -s and mkfs run without confirmation once pointed at a device, so the only real safeguard is verifying the target's identity — serial number or WWN via /dev/disk/by-id — before the first write, not after. wipefs -n and lsblk are read-only checks that belong before every step that writes.
