It matches the most obvious setup where the RAID contains just a GPT followed by a FFS partition, but indeed, there is room for improvement. We could have an installboot(8) option for that. Something like: installboot -o raid1_root_start=34 /dev/rdk1 bootxx_ffsv2 installboot(8) could detect the GPT-inside-RAID1 situation, inspect the GPT and set the appropriate value correctly.
