You need to use "-b /boot/boot" argument to install it. What is going in your case: BSD label metadata was stored in first sector of da0s1 and GEOM object of PART_BSD class was created. Then you added partitions, that starts from zero offset, i.e. it contains BSD label metadata. Then /boot/boot content was written into da0s1a, and it has overridden BSD label. But since da0s1a is separate GEOM provider, the spoiling did not worked for da0s1. --=20 WBR, Andrey V.
