How do you think file systems would be handled? Apple’s SCSI/FireWire/USB/Thunderbolt Target Disk Mode just made all disks available over the interface in a filesystem-agnostic manner. Would I be able to see my ext4 boot partition, ZFS arrays, and any attached volumes?
Yeah, but reflashing a motherboard is far less dangerous than reflashing a $30,000 car. Your computer couldn’t kill someone if something fails. As much as I hate this image and wished repair instructions were made public, this may be the wisest move from a liability perspective.
