Informed by reading the bsdinstall(8) scripts, I've been creating my own boot1.efifat thusly:
#!/usr/bin/env sh
TMPDIR=/mnt
rm -f /boot/boot1.efifat
newfs_msdos -F 32 -c 1 -L EFISYS -C 200m /boot/boot1.efifat
MD=$(mdconfig -f /boot/boot1.efifat)
mount -t msdosfs /dev/${MD} ${TMPDIR}
mkdir -p ${TMPDIR}/efi/boot ${TMPDIR}/efi/freebsd
cp -a /boot/loader.efi ${TMPDIR}/efi/boot/bootx64.efi
cp -a /boot/loader.efi ${TMPDIR}/efi/freebsd/
umount ${TMPDIR}
mdconfig -d -u ${MD}
Then I use `gpart bootcode -p /boot/boot1.efifat ...` as usual.
To avoid confusion and errors, I think a proper boot1.efifat should be put back into the base system so that people don't have to track the above recipe (which is likely to change).
