Yes export $DESTDIR via NFSv3

Your kernel needs to support (options NFS_ROOT). If you can't run
/boot/loader than define the rootfs in the kernel config (options
ROOTDEVNAME=\"ufs:/dev/ufs/rootfs\").

My questions is:
1) we are not telling the NFS server ip address in above two options. where
we will configure the server ip of NFS server in config options.
