                            hardware platform. These include a ``/boot/efi``
                            for x86_64 and Aarch64 systems with UEFI firmware,
                            ``biosboot`` for x86_64 systems with BIOS firmware
                            and GPT, and ``PRePBoot`` for IBM Power Systems.

                            Note: This command can not be used together with
                            ``autopart``, because ``autopart`` does the same
                            and creates other partitions or logical volumes
                            such as ``/`` and ``swap`` on top. In contrast with
                            ``autopart``, this command only creates
                            platform-specific partitions and leaves the rest of
                            the drive empty, allowing you to create a custom
