r353004:
Explicitly add opensolaris_load="YES" to loader.conf through the installer when installing the system on a ZFS root filesystem. For arm64, zfs_load="YES" does not add opensolaris.ko as a kld dependency, so add it explicitly to prevent boot-time failures out-of-box.
r353012:
Add a comment explaining why the opensolaris_load line in loader.conf is explicitly added.
