In zfsloader, the ZFS device identify structure is now zfs:pool/fs and the absolutely experienced file path structure is zfs:pool/fs:/path/to/file. The zfsboot boot block accepts the kernel/loader title in the structure pool:`fs`:`path/to/file` or, as ahead of, pool:`path/to/file`. The zfsboot boot block passes the GUIDs of the picked storage pool and dataset to zfsloader to be utilised as its defaults.
