Thanks, I have a legacy boot from an MBR disk to a GPT formatted disk with freebsd-on-zfs.
I see not much advantage with efi.

UEFI

… after the boot …

See for example <https://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface#Features>

… runtime services …

I should recommend having an EFI system partition (ESP) on any disk that might, in the future, boot in a UEFI environment; even if not a requirement in the current environment.

Forward-looking.
