In this code, da0 is the source disk, where the bootcode files are read.
It is mounted on /mnt. So there are two reasons that gpart cannot write
bootcode to da0p1. First, it is mounted, and second, it is filesystem
partition, not a freebsd-boot partition.
The target disk cannot be da0p1. Maybe it is a simple typo, and
either the second or third line was meant to be ada0 rather than da0.
