Also it says, that this type is used for second extended partition
chain. This means you can not just add type id to MBR scheme, because
this will lead to partition names collisions in GEOM_PART_EBR_COMPAT
mode. Anyway we don't handle this correctly, even if you will use
0x05/0x0f for second chain :)
