I don't know specifically if it was the bsdinstall program. I guess it was. It
was whatever is invoked after booting the install disk/image and then

I'd say if it's not working as suggested or implied then it's broken, or why
have the manual option at all? I don't expect the consequence of selecting
this option to be "doesn't install a kernel" or "everything is installed, it's
just not bootable" without notification.
I've not encountered the issue before because my installation context is
mostly bhyve-based so I just accept the defaults. Because this is bare metal,
I was hoping to optimise the SSD somewhat.

There should be a reason why this is selected as default. "Most x86 systems"
isn't enough. I'd fix this if I knew how. What is the GPT advantage?
thanks for the clarification
