Re: Crypto softraid is supported on GPT/UEFI boot and not just on BIOS/MBR boot, right?

By that logic, we should have quit using cheap disks when they went over
32MB. Or 120MB. Or 504MB. Or 128GB. Or ...
I have MBRs on 4TB SoftRaid volumes, works fine.

fdisk, make the "entire" disk (welll....the first 2TB) OpenBSD.
disklabel, change the boundaries of the OpenBSD part to be the entire
disk. Done.
