That image is not built the way >= 12.x installations operate by default. It will install an ESP with an \EFI\BOOT\BOOTx64.EFI (or something like this) while we now, by default, setup \EFI\FreeBSD\loader.efi and the appropriate efibootmgr to point at it. In the former setup, that's actually /boot/boot1.efi which may or may not do GELI correctly in the new world order -- I don't recall, it's kind of special. 2.) That invocation clobbers anything else that might've been trying to reside on your ESP. If you had any kind of dual-boot setup going (perhaps rEFInd + grub + freebsdloader) then you've immediately hosed it by overwriting the partition completely. Thanks, Kyle Evans
