There is something special. from fdisk(8) -A: "Modifies the GPT partition table entries on disk to put all available space not taken by -b into a single OpenBSD partition. The available space is first maximized by deleting all existing partition entries except those for APFS ISC, APFS, APFS Recovery, BIOS Boot, HiFive FSBL and HiFive BBL partitions. If APFS ISC, APFS, or APFS Recovery partitions are detected then existing EFI system partitions are also preserved. If the preserved EFI system partition has fewer blocks than the number requested with -b, the modified GPT is discarded." unlike most other machines some amount of apple bits need to be on disk https://github.com/AsahiLinux/docs/wiki/Open-OS-Ecosystem-on-Apple-Silicon-Macs That said, I don't have an apple arm machine and have never done an install on one.
