Right, this is what I meant by the EFI brick in my comment. And in my comment "I can't say I've heard of that happening", I meant bricking a device on a system update. That's the specific thing which seems to happen on occasion with macOS, but that I've not seen with Linux. I do grant that there have been some (very rare) instances like this where hardware can be bricked by a command run on a Linux system.
