partition that covers the end of the disk.

See: https://github.com/zfsonlinux/zfs/issues/1684
zfs: Don't look for devices only in /dev

If we don't give out a directory to 'zpool import', it will use libblkid
to automatically find all existing ZFS devices.

See: https://github.com/zfsonlinux/zfs/pull/2051
