Updates FreeBSD ZFS EFI and legacy boot code on GPT devices
Designed by Morgan Davis for use with FreeBSD 14 or later.
Usage: Run as root. For each GPT device with a freebsd-zfs partition, it shows you what steps will be performed, and asks you to type 'YES' before any updating takes place. Anything else skips that device.
Both the legacy freebsd-boot and efi partitions can be updated.
EFI updates are only offered if the existing installed boot code differs from the latest loader.efi file.
