Minor nit: GPT is unrelated here, but the disk needs to have space
for a new EFI System Partition (or already have one). You can UEFI-boot
MBR partitioned disks just fine.

I guess the main point of confusion is that you can't add /boot as a directory
to the mtree specials file or similar (or find/add some mtree notation that
allows it to be a file instead), and that you are not going to create
a directory /boot on updates (but would do so on new installs, via
sysinst at runtime, and not include the dir in any sets).
